An NFC device is quite complex: it has to support both ASK/BPSK modulation, variable data rates from 106kb/s to 848kb/s, different ASK modulation indices (8% to 100%), different card types (NFC-A/B/F), and various coding. It also has different operating modes such as Proximity-Inductively-Coupled Card (PICC) or card-emulation mode, ProximityCoupled-Device (PCD) or reader mode and Peer-to-Peer (P2P) mode. Furthermore, some PCDs transmit NFC-A/B/F ASK data in a polling loop manner.
