A subtle, well-designed diagnostics tool
For RFID Diagnostic Card
I’m very happy to have this ingenious little card. It’s so well thought-out and easy to use. As shown in the video the reader type is clearly shown by the corresponding LED, and the relative intensity easily determined by the brightness of the same LEDs. I like also that it can be placed in the wallet with only the indicator lights visible and it still gives an accurate reading. A very cool idea in an equally cool compact package.
