What is RFID eavesdropping?
Eavesdropping, like it sounds, occurs when an unauthorized RFID reader listens to conversations between a tag and reader then obtains important data. It is still necessary for the hacker to know the specific protocols and tag and reader information for this technique to work.
What devices use RFID?
