ISO/IEC 18092 (NFCIP-1)

ISO/IEC 18092 (NFCIP-1) defines the fundamental NFC communication interface and protocol for device-to-device data exchange. It specifies both active and passive communication modes at 106, 212, and 424 kbps, covering the physical layer, initialization, single device detection, and data exchange protocol. NFCIP-1 is the core peer-to-peer protocol that enables Android Beam (deprecated), Bluetooth/WiFi handover initiation, and other device-to-device NFC applications.
