Overview
ISO/IEC 15693-3:2026 is an international standard published by ISO and IEC that defines protocols and commands for communication between contactless vicinity integrated circuit cards (VICCs) and vicinity coupling devices (VCDs). This standard forms Part 3 of the ISO/IEC 15693 series for cards and security devices for personal identification, focusing specifically on anticollision procedures and transmission protocol for contactless identification cards designed for longer-range operation compared to proximity cards.
The main purpose of ISO/IEC 15693-3:2026 is to enable reliable, efficient communication with and selection of a specific card from among several present in the reader’s field. It includes detailed definitions of command types, data formats, security frameworks, card memory organization, and error handling. The standard also supports the integration of other card standards, such as ISO/IEC 7816-6, for interindustry data interchange.
Key Topics
- Anticollision Algorithms: Mechanisms to detect and communicate with one unique card among multiple VICCs in the reader’s field, preventing communication conflicts and ensuring accurate identification.
- Transmission Protocol: Bit-oriented, frame-based protocol detailing request and response formatting, including flags, command codes, data, and CRC.
- Initialization and Modes: Procedures for initializing communications and mechanisms for addressed, non-addressed, and select modes, allowing targeted operation with individual or groups of cards.
- Data Elements: Structure and use of key card identifiers, including unique identifier (UID), application family identifier (AFI), data storage format identifier (DSFID), and cyclic redundancy check (CRC) for data integrity.
- Security Framework: Optional features facilitating card and device authentication, secure messaging, and compatibility with cryptographic suites defined in the ISO/IEC 29167 series.
- Card Memory Organization: Guidelines for addressing and organizing card memory blocks, including lock status and security flags.
Applications
ISO/IEC 15693-3:2026 is widely applied in environments that require contactless identification technology at extended read distances. Key applications include:
- Access Control: Used in building, facility, and event access systems for efficient and secure personal identification.
- Library and Asset Management: Streamlines inventory management, check-in/check-out, and tracking of books or other assets using contactless cards or tags.
- Public Transportation: Supports mass transit, fare collection, and ticketing systems where rapid processing of multiple cards in proximity is essential.
- Healthcare and Medical Records: Ensures quick, contactless identification of patients and control of medical inventory in busy environments.
- Industrial Automation and Logistics: Identification and tracking of items, parts, or shipments in warehouses and manufacturing facilities.
- Retail and Loyalty Programs: Enables customer identification, membership verification, and usage of loyalty cards at checkout points.
The anticollision protocol and flexible, secure transmission make this standard suitable for deployments with high card densities and varied application requirements.
