This document specifies a half-duplex block transmission protocol featuring the special needs of a contactless environment and defines the activation and deactivation sequence of the protocol. This document is intended to be used in conjunction with other parts of ISO/IEC 14443 and is applicable to proximity cards or objects of Type A and Type B.

Overview

ISO/IEC 14443-4:2018 defines the transmission protocol for contactless proximity cards and security devices. It specifies a half‑duplex block transmission protocol and the activation/deactivation sequences tailored to the constraints of a contactless environment. The standard applies to Type A and Type B proximity cards/objects and is intended to be used together with other parts of ISO/IEC 14443 (physical, RF interface and anticollision) and ISO/IEC 7816‑4 (APDU/application protocol mapping).

Key topics and technical requirements

Half‑duplex block protocol: Block-oriented communication with defined prologue, information and epilogue fields for reliable transfer in a proximity environment.

Activation / deactivation sequences: Procedures for entering and exiting the PROTOCOL state, including RATS/ATS exchanges and interoperation with anticollision and initialization.

Frame and block formats: Definitions for length fields, prologue/epilogue bytes, chaining, block numbering and S/P/I block types for control, parameter exchange and data.

Frame waiting time (FWT) and extensions: Timing rules and mechanisms to manage response latency in contactless links.

Error detection and recovery: CRC mechanisms, retransmission rules, and presence check behaviors to handle collisions and noisy RF conditions.

Bit rates & framing options: Activation and negotiation of bit rates and framing (including provisions for specific bit‑rate framings such as fc/16, fc/8, fc/4, fc/2 and higher) and enhanced frames with error correction.

Enhanced error correction: Optional frame formats and Hamming‑based sub‑blocks and CRC_32 annexes for stronger error correction capabilities.

Parameter negotiation: Use of PPS, CID and parameter blocks to set interface bytes, block sizes and protocol parameters.

Annexes & examples: Multi‑activation examples, protocol scenarios and coding overviews to support implementation and conformance testing.

Practical applications

ISO/IEC 14443-4 is fundamental to systems using secure contactless communication:

Contactless payment cards and terminals (EMV implementations)

e‑Passports, national ID and secure identity documents

Access control and transit ticketing systems

NFC-enabled devices and readers that need ISO/IEC 7816 APDU transport over RF

Smartcard and secure element manufacturers implementing robust RF protocols

Who uses this standard

Smart card designers and secure element vendors

Payment scheme architects and terminal manufacturers

System integrators for transit, access control and identity systems

Test labs and conformity assessors validating contactless products

NFC developers requiring interoperability with ISO/IEC 14443 proximity cards
