Byte 1 : AFI for NFC-B polling
The AFI (Application Family IDentifier) is a parameter broadcasted by the reader within its NFC-B REQB/WUPB polling frames.
A card that does not belong to the specified Application Family remains silent (this aims to speed-up the anti-collision loop and avoid the reader to initiate a transaction with "useless" cards).
Remark : Set to
00 to target all cards (default)
