How the RFID-Based System Works

The system uses small, patch-like passive RFID tags placed directly on the patient’s body. Because these tags are passive, they require no batteries and instead harvest energy from a nearby RFID reader. The reader transmits radio waves that power the tags and capture their precise movements, allowing clinicians to monitor breathing patterns across multiple body locations at the same time, including the chest and abdomen.

This simultaneous multi-point measurement is a key advantage over many existing methods, as it gives a more complete picture of how the respiratory system is functioning during each breath cycle.

Addressing Limitations of Traditional Respiratory Monitoring

Conventional methods for assessing lung function often rely on imaging technologies such as X-rays and CT scans. These require dedicated hospital equipment, can expose patients to ionising radiation, and are not suitable for continuous or long-term monitoring outside a clinical environment.

The RFID-based approach sidesteps many of these drawbacks. It is wireless, portable, safe for repeated use, and does not require complex installation. This makes it particularly well suited for patients who need ongoing respiratory monitoring, such as those recovering from lung surgery or managing chronic respiratory conditions.

Xuezhi Zeng, Associate Professor at Chalmers’ Department of Electrical Engineering, described the goal clearly: “The goal is to enable more personalised and evidence-based rehabilitation” for patients in these groups.

Early Testing and Results

Initial testing was carried out at the simulation centre at Sahlgrenska University Hospital, where a commercial RFID reader system was used alongside a medical mannequin fitted with RFID tags on the chest. The results were promising, with the system successfully detecting even minor variations in movement between different measurement points on the body surface.

The study has been published in IEEE Access and received funding from Chalmers’ Area of Advance Health Engineering.

The Road Ahead

The research team is now working toward developing a custom-designed prototype specifically intended for clinical use. According to Zeng, the team hopes to begin testing the prototype on real patients within five years.

Looking further ahead, the long-term vision includes enabling continuous respiratory monitoring in the home. This could allow healthcare providers to detect early signs of respiratory deterioration in at-risk patients before a condition becomes serious, potentially speeding up the time to diagnosis and treatment.

For the many patients living with chronic lung disease or recovering from thoracic surgery, a lightweight, wearable, battery-free monitoring system could represent a significant improvement in quality of care and independence from hospital settings.

RFID Chips Embedded in Every Badge

Every ticket issued for the Masters Tournament now contains an embedded RFID chip. Augusta National’s own privacy policy makes no secret of it, stating that attendees consent to the club tracking badge locations through RFID readers positioned in and around Augusta National property. That network of readers gives the club real-time visibility into where each badge is at any given moment, including whether it has turned up at a known resale location.

The technology gives Augusta National something most event organizers can only dream of: a direct line of sight into the chain of custody for every single ticket. The moment a badge strays somewhere it shouldn’t, the club knows.

Severe Penalties for Resellers and Buyers

The RFID tracking doesn’t operate in isolation. Augusta National has paired the technology with a set of enforcement penalties that have made brokers and scalpers think twice. Original lottery winners whose badges are detected at resale locations face lifetime bans from the lottery, losing any future chance at attending the tournament. Long-term badge holders are stripped of their credentials entirely if a resale is detected. Anyone found on the grounds with a resold badge is removed immediately.

The club has been clear that it remains the only authorized source for tournament tickets, and it has shown a willingness to enforce that position with consequences that are effectively permanent for the individuals involved.

Secondary Market Takes a Hit

The results speak for themselves. What was once a booming resale operation near Augusta has nearly vanished. The ticket houses that used to operate in the area have closed up or moved on. One vendor told Yahoo Sports that only three badges were visible on StubHub for an opening round, listed at prices ranging from around $9,000 to nearly $70,000, a far cry from the days when inventory was plentiful.

SeatGeek, one of the larger ticket resale platforms in the US, announced early in 2026 that it would stop facilitating Masters ticket sales altogether, citing the pressure Augusta National continues to apply to secondary market vendors.

Some longtime Augusta brokers have adapted by selling directly during tournament week rather than through national platforms, but even that approach carries risk. As Nate Liberman from ticketing platform Tixr pointed out, the use of physical tickets creates a chain of custody problem that is difficult to work around when the issuer is actively monitoring badge locations.

A Model Other Organizers May Follow

Augusta National’s approach reflects a broader shift in how major event organizers are thinking about ticket distribution. By combining RFID tracking infrastructure with strict contractual penalties, the club has built a system that attacks the resale problem from two directions at once: technical detection and meaningful deterrence.

For the RFID industry, the Masters implementation is a high-profile example of what passive tracking at scale can accomplish in an access control and anti-fraud context. Whether other major sports and entertainment properties follow Augusta’s lead remains to be seen, but the results so far suggest the model is working.

The partnership brings two integrated digital solutions to one of the country’s busiest road corridors. The first is a Service and Penalty Management platform that replaces manual cash-based workflows with a fully automated system for processing traffic fines, road service fees, and other charges. The second is the TOLO Mini App, an RFID-integrated feature within the telebirr SuperApp that allows drivers to top up their Electronic Toll Collection (ETC) accounts and pass through toll gates without stopping.

How the RFID toll system works

Drivers register their vehicles and link them to their telebirr accounts through the TOLO Mini App. Each vehicle is fitted with a UHF RFID tag, and upon registration the tag ID, toll card ID, and number plate are all digitally linked in the system. When a vehicle approaches a toll gate, the RFID reader detects the tag from a distance, deducts the applicable fee from the linked telebirr balance, and grants immediate passage. No stopping, no cash, no queuing.

The Mini App also supports fleet management, allowing a single account holder to manage up to ten vehicles and process top-ups on behalf of other drivers. This flexibility makes the system practical not just for private motorists but for logistics operators and commercial fleet managers using the expressway regularly.

Replacing manual processes with automation

Before this system was introduced, ETRE relied on physical cash handling, manual bank transfers, and manual data entry into ERP systems. That approach created predictable problems: congestion at toll booths, revenue leakage, and a high risk of errors or fraud. The new platform addresses all of these directly.

The Service and Penalty Management component covers payments for overweight vehicle violations, unauthorised expressway entry, property damage fees, tow crane and tipper services, and vehicle parking charges. Management teams now have access to a real-time dashboard with Role-Based Access Control (RBAC), giving centralised visibility over all revenue streams and improving accountability across the board.

Part of a broader digital strategy

The launch is positioned as a contribution to Ethiopia’s Digital Ethiopia 2030 roadmap, with Ethio telecom using its telebirr SuperApp platform as the backbone for both services. Telebirr already has a substantial user base across the country, which is expected to support rapid adoption of the digital toll and payment features without requiring users to install separate applications.

For the RFID industry, the deployment is a solid example of UHF RFID being applied at scale in a developing market, integrated directly with a mobile payment platform rather than relying on dedicated hardware or card-based systems. It also demonstrates the growing appetite for frictionless, contactless payment infrastructure in African transport networks.

The Addis Ababa-Adama expressway is one of the most heavily trafficked routes in Ethiopia, and the efficiencies gained here could lay the groundwork for rolling out similar systems on other toll roads across the country.

CONTROLTEK, a leading provider of Electronic Article Surveillance (EAS) and RFID-based retail loss prevention solutions, has announced the appointment of Timothy Beckett as Key Account Manager for Canada. The move signals a deliberate push by the New Jersey-based company to grow its footprint in the Canadian retail market and deliver its technology portfolio to a wider customer base across the country.

Beckett steps into the role with a mandate to develop and manage strategic relationships with Canadian retailers, working to position CONTROLTEK’s EAS and RFID solutions as integral tools in their loss prevention and inventory management programmes. His appointment reflects the growing demand among Canadian retailers for advanced source-tagging, hard-tag, and RFID-enabled systems that reduce shrink, improve stock accuracy, and streamline supply chain visibility.

CONTROLTEK’s EAS and RFID Portfolio

CONTROLTEK has built a strong reputation in the North American retail sector through its comprehensive suite of loss prevention and inventory intelligence products. The company’s EAS offerings encompass AM (acousto-magnetic) and RF (radio frequency) systems, including pedestals, deactivators, detachers, and a broad range of tags and labels designed for both source tagging and in-store application. On the RFID side, CONTROLTEK provides UHF RAIN RFID tags, labels, and inlays suitable for apparel, footwear, accessories, and general merchandise, enabling item-level tracking from the distribution centre through to the point of sale.

The convergence of EAS and RFID within a single technology strategy is increasingly attractive to retailers seeking to address shrink while simultaneously gaining real-time inventory visibility. CONTROLTEK’s dual capability positions it well to support Canadian retailers navigating this transition, particularly as RFID adoption accelerates across the apparel and general merchandise sectors.

Growing Demand in the Canadian Retail Market

Canada’s retail industry has seen rising interest in RFID-enabled inventory management over recent years, driven by the need to compete with e-commerce, reduce out-of-stocks, and meet omnichannel fulfilment demands. At the same time, organised retail crime and general shrink remain pressing concerns for loss prevention teams. The combination of EAS for point-of-sale protection and RFID for end-to-end inventory accuracy addresses both challenges within a unified framework.

Timothy Beckett’s role will be central to educating prospective customers on the business case for these technologies and tailoring solutions to the specific operational requirements of Canadian retailers. Whether working with national chains or regional operators, his focus will be on delivering measurable return on investment through improved shrink reduction and inventory performance.

A Strategic Hire for Long-Term Growth

The appointment of a dedicated Key Account Manager for Canada underlines CONTROLTEK’s commitment to the market as more than an export opportunity. By placing an experienced professional on the ground, the company is investing in the kind of localised, consultative sales approach that complex EAS and RFID deployments require. Canadian retailers will benefit from direct access to specialist knowledge and a single point of contact capable of coordinating product selection, implementation support, and ongoing account management.

As RFID continues to mature from a pilot technology into a mainstream retail standard, appointments such as this one are a strong indicator of industry confidence in the Canadian market’s readiness for wider adoption.

Brooks Running, the Seattle-based athletic footwear brand, has eliminated shipping errors at its primary U.S. distribution centre after deploying an RFID-powered inventory intelligence solution from Sensormatic Solutions. The implementation has delivered a step-change in supply chain visibility, giving the company end-to-end control over its outbound fulfilment process.

At the heart of the deployment is Sensormatic’s TrueVUE Cloud platform, which gives Brooks a real-time picture of inventory movement from the moment product is tagged through to the point of shipment. On-demand RFID label printing and encoding is built into the workflow, and mobile RFID readers replace the need for fixed workstations on the floor, keeping operations flexible and scalable.

The results have been significant. Brooks is now achieving 100% accuracy across all picked and packed items leaving the facility. RFID scanning runs 26 times faster than the manual barcode processes it replaced, and automated shipping audits flag discrepancies in real time, allowing staff to correct mistakes before an order ever leaves the building. The knock-on effect has been a substantial drop in customer chargebacks, a persistent pain point for brands supplying major retail partners where compliance requirements are strict.

Steve LeClerc, Director of Distribution at Brooks Running, was direct about the business impact: “The speed and accuracy, along with the data we capture for accurate shipments, have been amazing.” That kind of feedback reflects what good RFID integration looks like in practice, where the technology becomes part of the daily operational rhythm rather than a bolt-on reporting tool.

Prior to the Sensormatic deployment, Brooks needed a solution that could be rolled out rapidly across the entire distribution centre without disrupting throughput. The brief was straightforward: make sure what ships matches exactly what was ordered. Sensormatic’s answer was an end-to-end system that ties together source tagging, mobile reading infrastructure, and API-level integration with Brooks’ existing warehouse management system. Every outbound shipment now has a complete digital audit trail attached to it.

From a supply chain technology standpoint, this deployment is a solid example of UHF RAIN RFID being used where it delivers genuine operational value rather than simply adding item-level data for its own sake. The combination of cloud-based visibility software, mobile readers, and tight WMS integration addresses the real-world complexity of a busy distribution centre without requiring a full infrastructure overhaul.

For other footwear and apparel brands managing high-volume outbound fulfilment, the Brooks Running case makes a clear argument for RFID at the distribution centre level. Shipping accuracy directly affects retailer relationships, chargeback costs, and brand reputation. When those three factors are all in play, the return on investment for a properly implemented RFID solution tends to justify itself quickly.

Sensormatic Solutions continues to expand its retail and supply chain RFID portfolio, and the Brooks partnership adds another data point to the growing evidence base for item-level RFID in athletic and performance footwear distribution.

The Core Principle: Electromagnetic Coupling and Backscatter

At its heart, RFID is built on a simple principle from physics: electromagnetic induction and, at higher frequencies, radiative coupling. If you have ever used a wireless phone charger, you already have an intuition for how passive RFID works. A wireless charger uses a coil to generate an alternating magnetic field, and a receiving coil in your phone converts that field back into electrical current. RFID uses the same underlying mechanism, but instead of just transferring power, the tag also modulates the signal to send data back to the reader.

In a passive RFID system, the reader transmits a carrier signal from its antenna. When this signal reaches a passive tag, the tag’s antenna absorbs enough energy from the electromagnetic field to power up its integrated circuit. The chip then modulates the impedance of its antenna, which alters the reflected signal in a process known as backscatter. The reader detects these tiny variations in the reflected signal and decodes them into meaningful data. There is no battery on the tag. The entire transaction is powered by the reader’s transmitted energy field.

This is where the parallel with wireless charging becomes particularly clear. Both technologies rely on resonant coupling between two antennas tuned to the same frequency. The difference is purpose: wireless charging maximises power transfer efficiency, while RFID optimises for data communication with just enough harvested energy to wake the chip.

Active vs Passive RFID: Two Fundamentally Different Approaches

RFID splits into two broad categories based on how the tag gets its power: active and passive. Understanding the distinction is essential because it determines read range, cost, battery life, and suitable applications.

Passive RFID tags contain no onboard power source. As described above, they harvest energy from the reader’s RF field, use it to power their IC, and respond via backscatter modulation. Because they rely entirely on the reader for power, their read range is limited by how much energy the reader can deliver to the tag. Passive tags are cheap to manufacture, often costing just a few pence each in volume, and they have an effectively unlimited operational lifespan since there is no battery to deplete. This makes them ideal for high-volume applications such as retail inventory, supply chain tracking, and access control.

Active RFID tags, by contrast, carry their own battery. This onboard power source means the tag can transmit its own signal rather than relying on backscatter. The result is significantly greater read range, often 100 metres or more compared to a few metres for most passive systems. Active tags can also support more complex sensors, larger memory, and continuous broadcasting (known as beaconing). The trade-off is cost and maintenance. Active tags are more expensive, physically larger, and their batteries eventually need replacing, typically after three to five years depending on beacon rate and environmental conditions.

There is also a middle ground: Battery-Assisted Passive (BAP) tags, sometimes called semi-passive tags. These contain a battery that powers the IC, but they still communicate via backscatter rather than active transmission. This gives them better read range and sensitivity than purely passive tags while keeping the communication method simple.

Frequency Bands: LF, HF, and UHF

RFID operates across several frequency bands, and the choice of frequency has a profound impact on read range, data rate, penetration through materials, and susceptibility to interference. The three primary bands are Low Frequency (LF), High Frequency (HF), and Ultra-High Frequency (UHF).

Low Frequency (LF) – 125 kHz to 134.2 kHz

LF RFID uses near-field inductive coupling. The tag and reader antennas behave like the primary and secondary windings of a transformer, with energy transferred through the magnetic component of the electromagnetic field. Because the wavelength at 125 kHz is extremely long (approximately 2,400 metres), the tag is always in the near field of the reader antenna, and propagation behaves according to magnetic field coupling rather than wave propagation.

LF signals penetrate water and animal tissue reasonably well, which is why this frequency band has been the standard for animal identification and livestock tagging for decades. It is also widely used in access control and vehicle immobiliser systems. The downside is short read range (typically under 10 cm) and slow data transfer rates. The low carrier frequency simply cannot support high bandwidth.

High Frequency (HF) – 13.56 MHz

HF RFID also operates primarily through inductive coupling, but at a much higher carrier frequency. The wavelength at 13.56 MHz is about 22 metres, so the tag is still typically within the near field of the reader, but the shorter wavelength allows for smaller, more efficient antennas and higher data transfer rates than LF.

The 13.56 MHz band is globally allocated for industrial, scientific, and medical (ISM) use, making it one of the most universally available RFID frequencies. It forms the basis for several important standards, including ISO 15693 for vicinity cards and ISO 14443 for proximity cards.

NFC: The HF Subset Everyone Knows

Near Field Communication, or NFC, operates at 13.56 MHz and is technically a subset of HF RFID. What distinguishes NFC is its standardised communication protocols (defined in the NFC Forum specifications and built on ISO 14443 and FeliCa) and its support for peer-to-peer communication. While traditional HF RFID is strictly a reader-to-tag relationship, NFC devices can operate in three modes: reader/writer mode, card emulation mode, and peer-to-peer mode.

This flexibility is what makes NFC so versatile. Your smartphone can read an NFC tag (reader/writer mode), emulate a contactless payment card (card emulation mode), or exchange data with another NFC device (peer-to-peer mode). The intentionally short read range of NFC, typically 4 cm or less, is a feature rather than a limitation. It provides an implicit layer of security since you must physically bring the two devices close together to establish communication.

Ultra-High Frequency (UHF) – 860 MHz to 960 MHz

UHF RFID represents a fundamentally different approach to the RF link. At these frequencies, the wavelength is approximately 33 cm, meaning the tag is typically in the far field of the reader antenna. Communication relies on radiative coupling and backscatter rather than inductive coupling. The reader transmits a continuous wave, and the tag modulates its radar cross-section by switching its antenna between matched and mismatched impedance states. The reader then detects these amplitude or phase changes in the reflected signal.

This far-field operation is what gives UHF RFID its impressive read ranges, commonly 5 to 12 metres with standard passive tags and commercial readers. Data rates are also substantially higher than LF or HF, enabling rapid inventory of hundreds of tags per second. The RAIN RFID alliance, which promotes the GS1 UHF Gen2 standard (ISO 18000-63), has driven massive adoption of UHF RFID in retail, logistics, healthcare, and manufacturing.

However, UHF has its challenges. Water absorbs UHF energy and metals reflect it, causing multipath interference and detuning of tag antennas. Significant engineering goes into designing UHF tags that perform reliably on or near metal and liquid surfaces, using techniques such as raised antenna designs, spacer layers, and impedance-matching strategies.

The specific frequency allocation within the UHF band varies by region. In Europe, ETSI regulations permit operation between 865.6 MHz and 867.6 MHz, while the FCC in the United States allows 902 to 928 MHz. This regional variation must be accounted for when deploying global RFID systems.

Inside an RFID Reader: Antenna, Decoder, and Controller

An RFID reader is more than just an antenna. It is a carefully engineered system comprising several key components working together.

The antenna is the most visible part. In UHF systems, this is typically a circularly polarised patch antenna designed to maintain consistent read performance regardless of tag orientation. In HF and LF systems, the antenna is usually a coil or loop antenna optimised for magnetic coupling. Reader antennas come in various form factors, from handheld devices to fixed portal readers used in warehouse dock doors.

Behind the antenna sits the RF front end, which handles signal generation, amplification, and reception. The transmitter generates the carrier signal at the required frequency and power level, while the receiver must detect the extremely weak backscatter signal from the tag. The difference in power between the transmitted signal and the received backscatter can be 60 dB or more, making receiver sensitivity and noise floor critical design parameters.

The decoder, or baseband processor, extracts the data from the demodulated backscatter signal. It handles the protocol-specific encoding schemes. For example, UHF Gen2 uses a combination of PIE (Pulse Interval Encoding) for the reader-to-tag link and FM0 or Miller encoding for the tag-to-reader link. The decoder must also manage the anti-collision algorithms that allow a single reader to communicate with multiple tags simultaneously without data collisions.

Finally, the controller manages the overall reader operation, handles communication with host systems (via Ethernet, USB, serial, or wireless interfaces), and implements the higher-level application logic. In modern readers, this is often a capable embedded processor running a real-time operating system.

The Physics of Energy Harvesting

One of the most remarkable aspects of passive RFID is the tag’s ability to harvest enough energy from the reader’s field to power a silicon integrated circuit. At UHF frequencies, a typical passive tag IC requires between 15 and 30 microwatts to operate. The tag antenna must capture this power from the incident RF field while simultaneously modulating the backscatter signal for data transmission.

The tag IC contains a charge pump rectifier circuit that converts the received AC signal into DC voltage to power the chip’s digital logic. As reader-to-tag distance increases, the available power drops according to the inverse square law in the far field (for UHF) or the inverse cube law in the near field (for LF and HF). This power budget is ultimately what limits the read range of passive RFID systems.

Advances in IC fabrication technology have steadily reduced the power requirements of RFID chips, which directly translates into improved read range and reliability. Modern UHF RFID ICs from manufacturers like Impinj, NXP, and EM Microelectronic achieve sensitivity levels below -22 dBm, a figure that seemed unreachable a decade ago.

Bringing It All Together

RFID is not a single technology but a family of technologies united by a common principle: using radio frequency electromagnetic fields to identify and track objects without physical contact or line of sight. Whether it is an LF tag embedded in a cow’s ear, an NFC chip in a smartphone enabling a contactless payment, or a UHF label on a pallet racing through a distribution centre, the underlying physics of electromagnetic coupling, energy harvesting, and backscatter modulation remain consistent.

Understanding these fundamentals is what separates those who deploy RFID effectively from those who treat it as a black box. The choice of frequency band, active versus passive architecture, antenna design, and reader configuration all flow from the physics. Get those foundations right, and RFID delivers the kind of reliable, scalable automatic identification that drives modern supply chains, security systems, and connected products.

The old system relied on manual counting with a 15-day reporting lag, meaning problems were always discovered well after the fact. The hospital’s hotelaria team was burning through 320 hours every month just trying to keep up with physical counts. Meanwhile, roughly 800 replacement pieces were being ordered each month at a cost of R$ 104,000.

To tackle the problem, the hospital partnered with Brazilian RFID integrator Inovacode to deploy a UHF RFID tracking system across its linen supply chain. The solution centered on washable textile RFID tags built around the Impinj Monza R6-P chip, each certified to survive 200 industrial wash cycles. Over an 18-day tagging sprint, all 40,000 pieces received individual UHF labels.

Inovacode installed portal readers at six critical transition points: the laundry exit and return dock, three internment floors, the surgical center, and the emergency room. A middleware layer with a REST API fed real-time tracking data into the hospital’s existing management system, while a dedicated dashboard gave staff instant visibility into item locations, wash cycle counts, and low-stock alerts.

The entire rollout took 90 days and cost R$ 780,000. The results, however, paid that back in just over eight months.

Monthly losses dropped from 800 pieces to just 41, a 94.9% reduction. One of the most valuable insights came from the data itself: 61% of all losses were happening in transit between the external laundry facility and the hospital. With that bottleneck identified, the hospital could apply targeted corrective measures rather than guessing where items were disappearing.

Monthly replacement spending fell from R$ 104,000 to R$ 9,200, saving nearly R$ 95,000 per month. The manual counting burden shrank from 320 hours to 22 hours monthly, freeing staff for higher-value work. Wash cycle tracking also flagged items nearing end-of-life, cutting premature disposal by 18% and extending the useful lifespan of expensive surgical textiles.

Over the first 12 months, accumulated savings reached R$ 1.13 million, exceeding projections by 45%. For hospital administrators weighing the costs of RFID adoption, Albert Einstein’s experience offers a clear message: the technology does not just reduce losses, it makes the entire linen lifecycle visible and manageable in ways that manual processes never could.

The suite of applications and services leveraging existing cameras, RFID and vision systems integrates with more than 80 applications currently in use in correctional facilities in the U.S. The RFID provides offender management, jail management and case management systems.

Correctional professionals have one the highest rates of non-fatal, work-related injuries of any profession in the United States, and inmate altercations continue to be problematic. But modernizing the technology and tools that are used by officers has the potential to create high levels of situational awareness, increase officer retention and decrease dangerous situations. Command Cloud brings all the critical information right to officers and creates a communications framework to empower teams to improve safety and security.

Ken Dalley Founder and Chief Warrior of GUARDIAN RFID.

The RFID and facial recognition systems along with machine learning and mobile technologies provide real-time awareness of what is happening in a correctional facility, unifying data from disparate systems into one place providing context and allowing the relevant information for quick decision making by managers and officers.

The RFID aspect of the system provides an awareness for the correctional officers, alerting to the improper movement of missing items such as workshop tools or kitchen equipment, manages movement of people, preventing access to restricted areas and enables efficient record keeping. It also allows immediate identification for access control, medical treatment.

The RFID technology is combined with an encryption that ensures no inmate can ever be associated with more than one wristband tag. The High Frequency RFID as well as Active RFID integrates with mobile devices as well as PoE ForceField readers.

Similar systems can be found in UK prisons ensuring inmates requiring special care are checked upon at specified intervals.
