Key performances of the communication
- 1 - Tag needs power No functionality when out of reader range - 2 - Tag within reader range Tag wakes up - 3 - Tag receives Data Tag Rx processing - 4 - Tag sends Responses By field shortage - 5 – Reader needs to detect Load modulation level - 6 – Reader needs to process Reader sensitivity Reader

NFC - Communication modes
1. Active Communication mode In active communication mode, both the initiator and the target use their own generated RF field to enable the communication. • Standard mode for peer to peer (p2p) communication 2. Passive Communication mode In passive communication mode, the target answers to an initiator command in a load modulation scheme. The initiator generates the RF field. • Extended mode for p2p and RFID communication Benefit in p2p mode: Target saves power
