# Radio Frequency Identification (RFID) & Near Field Communication (NFC)
### Replay Attacks
Replay attack is a technique where a malicious user could implement a device to intercept a NFC transaction and redeem it later, using other device or even in different location.
### Relay Attack
The relay attack is a technique where a malicious user implements a man in the middle attack. The attacker(APDUer) is capable to intercept, manipulate and change the transaction in real time to take advantage of it.
