xLED Field Tester Card
The xLED is designed to show the ideal location, rotation, and orientation to position one of our x-series chips when presenting to a reader.
Not for implantation! The xLED is made with thin-walled industrial grade glass, non-biocompatible epoxy resin, and would probably not even stand up to autoclave sterilization. Besides, you wouldn’t be able to see the LED while holding it up to a reader anyway.
Unlike the RFID Diagnostic Card, the xLED is tuned for a single frequency. If you need to test a mysterious reader to determine what frequency it operates on, then check out the RDC.
