These paper-thin, adhesive EPCglobal Gen2 tags work with Simultaneous UHF RFID reader and can be stuck to practically anything you can imagine. The tags can read and be written to — and also have a kill feature. Each tag comes with a TID (Truly Unique ID) that can’t be changed, but there’s plenty of memory for you to write and read from.
Note: These tags are suitable for the reader below. For other readers we cannot confirm suitability. Tags cannot be returned.
