A luxury product can carry a registered NFC tag and still require physical inspection. Useful authentication design connects the tag, the item record and a process for handling uncertain results.
Decide which claim you need to check
These are different questions: Does the tag return valid authentication data? Does the item match its product record? Is the seller authorised? Is the product in acceptable condition?
NXP's NTAG424 DNA documentation describes dynamic authentication using AES-128. Hashentic validates supported secure-chip responses and checks for reused data. For current options, see the EM4425, NTAG424 DNA and NTAG215 guide.
The physical attachment matters. Inspect whether a genuine tag could be moved to a different item and how staff would recognise damage or replacement. A registered tag is not a substitute for inspecting the bag, watch or bottle.
Plan placement around the finished product
- Bags: test an inlay in the lining or a suitable label, including bending, wear and attachment.
- Watches: test a non-metal location, strap or associated card. A chip inside a metal case needs a suitable antenna and a verified reading position.
- Wine: test the label around foil, glass and liquid. A tag response does not establish the contents or seal condition.
The chip is only part of the label. Antenna dimensions, substrate and attachment influence the finished result. Use placement examples as pilot ideas, not as a guarantee that the same construction works on every product.
Use scan signals to investigate distribution
Hashentic can detect scans outside configured markets and other suspicious patterns, including implausible travel, scan spikes and counter regression. Availability depends on the fraud module and the location data available.
Review an alert with its score, signals and related scans. A customer travelling with an authentic product can also generate an unexpected location. The team can acknowledge, dismiss or confirm an alert and configure a workflow response.
A market-boundary signal does not automatically determine whether a sale was authorised or unlawful. Your distribution records and commercial process supply that context.
Build a workable resale or returns process
- Look up the product record and perform the tag check.
- Compare the item with the model, serial and documents supplied.
- Check the order or seller information in the relevant system.
- Inspect condition, attachment and signs of replacement.
- Route missing, damaged or suspicious identifiers to staff review.
Ownership transfer, resale payments and warranty decisions require a defined process and any necessary external integration. They are not automatically created by placing an NFC tag on an item.
Measure reading success, staff review time and the outcome of exceptions in a pilot. Use the returns workflow guide and pilot checklist, then bring a product sample to a demo.
