Topic: 14443-4 Type B Relay
I'm doing some research on 14443-b cards, and, I'm trying to do a relay attack. My setup works fine, with a 14443-A card, with the software nfc-relay-picc. As stated in the man pages it does not support Type B cards.
I was wondering why, and if I were able to build it my self. I have 2 types of readers ACR122u and the SCL 3711 but i have read some where that card emulation for Type B doesnt work at all for NXP.
Is that the reason why there is no relay tool/script for type B cards?
