ISO/IEC 18092:2023

Overview

ISO/IEC 18092:2023 - Near Field Communication Interface and Protocol 1 (NFCIP‑1) defines the interface and transport protocol for short‑range NFC communication using inductively coupled devices at a centre frequency of 13.56 MHz. The third edition updates and harmonizes NFCIP‑1 with NFC Forum digital protocol work and introduces support for NFC security features for the Target role. The standard supports both active and passive communication modes and defines how devices initialize, activate and exchange data over the RF interface.

Key technical topics and requirements

• RF interface at 13.56 MHz: physical RF field parameters, detection and timing requirements.
• Bit rates and timing: supported data rates are 106, 212 and 424 kbit/s (denoted f/128, f/64, f/32).
• Modulation, coding and frame format: specified modulation schemes, coding rules and RF frame structure for reliable data transmission.
• Active and passive communication modes: electrical and protocol differences for devices that generate an RF field (active) or are powered by the field (passive).
• Initialization and anti‑collision: procedures and conditions for device discovery, initialisation, RF collision avoidance (RFCA) and Start‑of‑Device‑Detection (SDD).
• Transport protocol and activation flow: commands and flows for Attribute, Wakeup, Parameter Selection, Data Exchange, chaining (more information), timeout extension and deactivation (Deselect/Release).
• Interchange rules: information interchange relies on prior agreement between parties on interchange codes and data structures.
• Conformance and annexes: CRC calculation (normative) and SAK information (informative).
• Normative references: includes ISO/IEC 13157‑1 (NFC‑SEC), ISO/IEC 14443‑2/3 and ITU‑T V.41.

Practical applications

• Enabling peer‑to‑peer NFC communications between smartphones, tablets and accessories.
• Interconnection of computer peripherals and small consumer devices where short‑range, low‑power wireless links are required.
• Implementing transport and activation flows for NFC‑enabled networked products and consumer electronics.
• Basis for interoperability testing, firmware/firmware stack development and device certification.

Who should use this standard

• NFC chipset and module designers, embedded firmware engineers and hardware designers.
• Mobile OEMs, consumer electronics manufacturers and accessory vendors integrating NFC.
• Standards engineers, interoperability test laboratories and security architects (refer to ISO/IEC 13157‑1 for NFC‑SEC).
• Product teams implementing NFC transport, initialization and collision control logic.

Related standards

• ISO/IEC 13157‑1 (NFC‑SEC), ISO/IEC 14443‑2 and ISO/IEC 14443‑3 (contactless proximity), ITU‑T V.41.
• NFC Forum Digital Protocol and Activity Technical Specifications - harmonization targets for interoperability.
