Abstract
A proximity check ensures that a card is physically close to the reader device in order to inhibit relay attacks. The proximity check makes relay attacks more difficult because an additional channel must be intercepted and/or spoofed or relayed. This solution can be used for any kind of short-range communication, including Near Field Communications (NFC).
