This tool is awesome! Find out what the frequency, field strength, and duty cycle of any passive LF/HF reader!

The RFID Diagnostic Card is a thin, flexible, credit card sized device that can tell you the frequency, field strength, 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 Card up against the reader and find out if the reader is active, approximate range/field strength, what frequency it's 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!

great item for developing RFID and NFC systems

I ordered a few for my self and friends so we can use it for developing RFID and NFC badges.
This is really handy to give a indication of the antenna's are good and there is RF power.

A subtle, well-designed diagnostics tool

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.
