RFID & NFC Diagnostic Card


Cyborg Centres KSEC Packages

The RFID Diagnostic Card 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 it. You can easily slap the RFID Diagnostic Card up against the reader and find out if it’s active, what frequency it’s operating at, and what the duty cycle of the reader is. This tool is designed to easily fit in any card carrier, wallet, or purse, and you can see the frequency indicator LEDs without even having to remove the RDC!
