The RFID Diagnostic Tool is a thin, flexible, credit card sized device that can tell you the frequency and duty cycle of any passive low or high frequency RFID/NFC reader, payment terminal, etc. Let's say your school, office or apartment building has an RFID reader securing the front door, but you don't know anything about what kind of system it is. You can easily slap the RFID Diagnostic Tool up against the reader and find out if the reader is active, what frequency it is operating at, and what the duty cycle of the reader is. The tool is designed to easily fit in any card carrier, wallet or purse, and you can see the frequency indicator LEDs without removing the tool from your wallet!
