Silent® NFC RFID Inlay 

The Silent® NFC RFID Inlay is designed to provide you with a unique tyre ID that essentially gives you a certificate of provenance that follows the tyre during its lifetime: manufacture, distribution, operation, repair, reuse, recycle and resell. The key practical feature of the batteryless anti-metal Tag, which itself reduces interference from the metal in the tyre, is that it comes in two formats to meet the needs of manufacturers, being fixed to the tyre either as an inlay or a patch. Using UHF the tag interacts remotely in real time with industrial  RFID readers and using NFC the tag can be seen directly with our purpose built Smartphone App.

This tag is an inlay; it is used by tyre makers only in the manufacturing process of a tyre.
