When Marks & Spencer first began experimenting with RFID technology back in 2003, few could have predicted the journey that lay ahead. Nearly two decades of trial, error, and persistence have turned the British retail icon into one of the most comprehensive adopters of item-level RFID tagging in the world. But it was far from a smooth ride, particularly when it came to beauty products and the thorny problem of metal interference.
M&S started its RFID journey with a modest pilot project tagging men’s suits. The early results were promising enough to justify further investment, but progress was slow. The technology was expensive, with tags costing roughly five times what they do today, and the business case was still being built one department at a time.
The Beauty Product Problem
As M&S expanded RFID tagging across its non-food product lines, beauty and cosmetics products emerged as the most stubborn challenge. The physical properties of these items, including metal components in packaging, foil-lined containers, and liquid contents, created significant interference with radio frequency signals. Standard RFID tags simply could not deliver reliable reads when attached to products containing metal or liquids.
Working closely with longtime partner Avery Dennison, M&S invested years in developing specialised tag formats to overcome these obstacles. The collaboration produced 10 distinct tag formats and, because the retailer uses different colour codes for various product categories, a total of 70 tag variations. Some were designed specifically for apparel, others for beauty products, and still others for items containing metal or liquids. Each tag also had to meet the aesthetic standards demanded by cosmetic manufacturers, adding another layer of complexity.
Overcoming Senior Management Resistance
Perhaps even more challenging than the technical hurdles was the battle for internal buy-in. Richard Jenkins, M&S’s head of loss prevention and the driving force behind the RFID programme, has spoken candidly about the resistance he faced from senior leadership. There were individuals in senior positions who lacked understanding of the technology yet spoke with great confidence about its limitations. During particularly difficult periods, Jenkins and his team had to fight against active de-investment in the programme.
To counter this scepticism, M&S established a cross-functional steering committee that brought together representatives from corporate leadership, IT, store operations, and finance. Retail and store staff provided frontline feedback on deployment issues, while finance executives helped build a rigorous business case demonstrating clear return on investment for each phase of the rollout.
Testing, Validation, and Results
M&S took a methodical approach to validation, constructing a mock store at its headquarters to test tag performance across different materials before rolling out to live retail environments. This careful testing regime helped the team achieve consistent, accurate reads even on traditionally difficult product categories.
The results speak for themselves. SKU accuracy improved from just 68 per cent when the project expanded to a full product range in 2014, to an impressive 91.5 per cent by the second half of 2021. The retailer now uses approximately 350 million RFID tags per year across its stores.
Lessons in Persistence
The M&S story offers several valuable lessons for any organisation considering RFID adoption. First, technical challenges like metal and liquid interference are solvable with the right partnerships and sufficient investment in tag development. Second, internal resistance from senior management can be just as significant a barrier as any technical limitation. Building a cross-functional team with clear ROI metrics is essential for maintaining momentum. Third, bringing software development in-house gave M&S greater control and agility, helping the retailer adapt the technology to its specific needs.
M&S’s own-brand business model also proved to be a strategic advantage, enabling tagging at source rather than in-store. This simplified logistics and reduced costs, a benefit that retailers relying heavily on third-party brands may find harder to replicate.
Today, M&S continues to push the boundaries, exploring robotic tag reading in stores and planning new formats where automation can track every item entering and leaving in near real time. The retailer’s RFID journey is a testament to what persistence and strategic thinking can achieve, even when the odds and the boardroom seem stacked against you.
