Peer-to-peer mode (P2P) for Near Field Communication (NFC) is a mode where two NFC devices can directly communicate with each other.

Peer-to-peer mode (P2P) for Near Field Communication (NFC) is a mode where two NFC devices can directly communicate with each other. Peer-to-peer mode is one of NFC's three operating modes (besides reader/writer mode and card emulation mode) and is standardized in ISO/IEC 18092 (NFCIP-1) and adopted by the NFC Forum's Analog and Digital protocol specifications.

NFC peer-to-peer mode supports different communication modes between two devices:

  • Active mode, where both devices alternately generate their own HF field.
  • Passive mode, where one device generates the HF field (similar to a contactless smartcard reader) and the other device operates as a passive target (similar to a contactless smartcard).
