RFID isn't spoofable? I thought it was.

Clipper cards use NFC, and there's at least some encryption protecting them - I don't believe they can be copied and spoofed the way common RFID tags can.

> The card operates on the 13.56 MHz range putting it into the Near Field Communication category (rather than RFID, as is commonly misconceived).

The important distinction isn't really the frequency. It's that the card has an actual circuit that performs some crypto handshake with the reader. It's not just static information encoded that anyone can just read and duplicate.

Mifare cards are generally spofable is as long as you know the keys. Which you can extract out of the air with a computer and some equipment.
