Seritag has launched the NFC Checkpoint, a purpose-built NFC tag designed for proof of presence verification across delivery, workforce tracking, and site compliance scenarios. The product has already gained significant traction following its adoption by Deliveroo for driver check-ins at collection points.
The NFC Checkpoint is a double-sided custom printed PVC tag measuring 1.2mm thick. It is both waterproof and dustproof, with an integrated antenna and chip sealed within the body. Two chip variants are available – the NTAG213 for standard applications, and the NTAG424 for environments where anti-cloning encryption security is required. The tags come in 60mm and 100mm sizes and are compatible with both Apple and Android smartphones.
The concept behind the product is straightforward. A checkpoint tag gets installed at a fixed location, such as a depot entrance, a building lobby, or a patrol route marker. When a worker, courier, or contractor arrives, they simply tap their phone against the tag. That single tap logs a timestamp, the user’s location, and their user ID, then transmits the data securely to whatever backend system the organisation is using.
What makes this approach stand out from alternatives is the security model. GPS-based check-in systems have long been vulnerable to location spoofing, and QR codes can be photographed and shared between users. An NFC tap requires genuine physical proximity to the tag, which eliminates both of those attack vectors. For organisations running the NTAG424 variant, there is an additional layer of protection through cryptographic authentication that prevents tag cloning.
The practical applications span several industries. Courier and delivery companies can use the tags for depot registration and route verification. Facilities managers can track contractor attendance without relying on paper sign-in sheets. Security firms can verify that patrol officers are physically visiting each checkpoint on their rounds. And any business with shift workers can use them as a frictionless clock-in and clock-out system, replacing badge readers or manual timesheets.
The simplicity of the interaction is worth highlighting. There are no apps to open, no forms to fill out, and no passwords to remember. A single tap handles everything, which means adoption rates tend to be high even among less tech-savvy users.
With workforce verification and compliance becoming increasingly important across regulated industries, products like the NFC Checkpoint address a real operational need. The combination of physical security, ease of use, and flexible deployment makes it a practical solution for organisations looking to move beyond honour-based attendance systems.
