The RFID Field Detector Card helps determine if a RFID reader is using Low Frequency or High Frequency RFID.
When the card is held up to the reader, the "LF" LED will illuminate if the reader is using Low Frequency (125kHz) RFID. The "HF" LED will illuminate if the reader is using High Frequency (13.56 MHz) RFID. Both LEDs will illuminate if the reader uses both frequencies.

NO BATTERIES NECESSARY! The card is powered from the radio signal from the RFID reader :)

SIZE OF A CREDIT CARD! The card will fit in your wallet, however, be careful because the components are exposed.

I enjoy everything RFID and this is a fun tool. The original design was by Corey Harding and he gave me permission to remix it and offer it for sale.

It's a great tool for determining if a RFID reader is using LF or HF RFID. Great for red-team engagements or learning!
