NFCKill UHF

UHF tag destruction is difficult for multiple reasons:

• Antenna shapes make induction more difficult (UHF tags typically have “Wing” style antennas, vs the more easily induced “Spiral” antennas in HF tags)
• Antenna configuration makes high-current induction difficult
• Tag orientation is more important – tags have to be in the induction plane but are often embedded within products (clothes, shoes, devices, etc) in an unknown configuration.

The NFCKill UHF device is built specifically for UHF RFID tags at an industrial scale. It has been proven specifically effective for key clients:

• Destruction of UHF tags embedded in shoes
• Destruction of UHF tags embedded in clothes
• Destruction of UHF tags embedded in industrial products
• Disabling RFID tags where the supplier does not provide the tag password
• Disabling anti-theft RFID tags that were not disabled by the retailer
• Disabling UHF tracking tags embedded to control brand and limit item resale.

UHF RFID Background

UHF Tags are very commonly embedded in consumer products. Because of UHF tags’ longer read range, tags are often used during manufacturing for logistics and quality control. However, UHF tags are often used for other less ethical reasons:

• Brand Control: Large brands often embed UHF tags in clothing/shoes/apparel allowing brands to track individual items and force distribution to their approved channels only. While there are legitimate uses, specifically to prevent counterfeits or retail theft, many brands use RFID / UHF as a form of brand control. Companies specialized in clothing resale or modification (ie customized sneakers) are often subject to legal threats via the brand, which tracks down makers via the RFID tags embedded in the items – even though their work is protected via the first-sale doctrines.
• Consumer Tracking: Because UHF tags have a unique signature and cannot be easily removed from clothing/shoes / etc, they are used to track / spy on customers. This can be in the form of data collection in retail environments (following consumer behavior in shopping malls, tracking a customer’s path, habits, etc)

Beyond standard reasons for tag management, there are many reasons that being able to disable UHF RFID Tags is important: Privacy & security.
