PN531
μC based Transmission module
4.2.2 PASSIVE NFC MODE
Passive NFC Mode means that the target answers to an initiator command in a load modulation scheme.
The initiator is active i.e. generating the RF field.

Figure 6 passive NFC Mode
The PN531’s firmware and contactless UART handle the NFC protocol.
4.3 Card Operating mode
The PN531 can be addressed like a FeliCa
TM
or ISO14443A/ MIFARE
card. This means that the PN531 in
combination with a secure μC may acts as an ISO14443A /MIFARE
or FeliCa
TM
card.
