Full title and description

St ISO/IEC 18000-63:2021 — Information technology — Radio frequency identification (RFID) for item management — Part 63: Parameters for air interface communications at 860 MHz to 960 MHz using the GEN2v2 (ISO/IEC 18000-63) protocol

Abstract

This standard specifies the air interface protocol and parameters for passive RFID systems operating in the UHF band (approximately 860 MHz to 960 MHz) using the Gen2v2 / ISO/IEC 18000-63 framework. It defines communications between interrogators (readers) and tags, including modulation, coding, link timing, commands, responses, and optional features to support item management applications such as inventory, tracking, and authentication.

Scope

ISO/IEC 18000-63:2021 defines air interface communications for RFID devices operating in the UHF band intended for item management. The scope includes physical layer characteristics (frequency ranges and channelization), modulation and coding schemes, link timing and frame structures, inventory and singulation procedures, command set and response formats, optional features (e.g., authentication commands, privacy protections, and extended memory operations), and conformance requirements for reader and tag interoperability. It is intended for passive and battery-assisted passive tags used in supply chain, retail, logistics, asset management, and similar item-level applications.

Key topics and requirements

• Definition of air interface parameters for 860–960 MHz UHF RFID systems following GEN2v2/ISO/IEC 18000-63.
• Physical layer: frequency ranges, channel plan, transmitter and receiver requirements, and power limits consistent with regional regulations.
• Modulation and coding: supported modulation schemes (e.g., ASK/PR-ASK), link coding, and data rates.
• Protocol and commands: core and optional commands for inventory, singulation, read/write memory, tag access, kill, lock, and security/authentication.
• Timing and framing: command/response timing, slot-based inventory mechanisms, and anti-collision procedures for large populations of tags.
• Security and privacy: optional authentication mechanisms, access control, and provisions to support privacy-preserving operations.
• Interoperability and conformance: requirements to ensure cross-vendor compatibility between readers and tags implementing the standard.

Typical use and users

This standard is used by RFID system designers, tag and reader manufacturers, integrators, test laboratories, and organizations implementing item-level tagging solutions. Typical applications include retail inventory and replenishment, supply chain and logistics tracking, asset management, pharmaceuticals, libraries, and any environment where interoperable UHF RFID item-management solutions are required.
