Overview
ISO/IEC TR 29162:2012 is a Technical Report that gives practical guidance for writing and reading data structures across AIDC media (automatic identification and data capture) used in the supply chain - including linear bar codes, two‑dimensional symbols, and RFID transponders. It explains common data structures, promotes compatibility between optical and radio‑frequency media, and clarifies how to apply existing encoding and syntax standards when exchanging item and transport data.
Key topics and requirements
- Scope and purpose: Guidance for encoding both Unique Item Identifiers (UII) and item‑attendant data on various AIDC media to support reliable supply‑chain operations.
- Syntax for high‑capacity media: Use of ISO/IEC 15434 message and format envelopes to contain multiple data formats and enable transfer of complex records in 2D symbols and high‑capacity tags.
- RFID encoding rules: Overview of RFID encoding approaches and compatibility considerations with ISO/IEC 15961 / ISO/IEC 15962 for air‑interface encoding and Application Family Identifiers (AFIs).
- Unique Item Identifier (UII): Guidance on UII constructs, numbering systems and tag memory organization for efficient RFID inventorying.
- Semantics (data identifiers): Use of ASC MH10 Data Identifiers (DIs) and GS1 Application Identifiers (AIs) (ISO/IEC 15418) to define the meaning of encoded fields.
- Data carrier identification: Use of ISO/IEC 15424 identifiers so systems can detect whether data came from RFID, bar code, 2D symbol, or key entry.
- Encoding options for item attendant data: Methods including directory vs. no‑directory, packed objects, and Tag Data Profiles to store non‑UII data in RFID memory.
- Resilience and fallback: Recommendation to provide optical backups (ISO/IEC 24729‑1) or other carrier identifiers to mitigate tag or reader failures.
Practical applications and who uses it
ISO/IEC TR 29162:2012 is valuable for:
- Supply‑chain architects and systems integrators designing item identification and tracking
- RFID implementers and tag memory planners ensuring inventory efficiency and compatibility with existing bar‑code systems
- Label designers and packaging engineers embedding multi‑field data on 2D symbols
- Standards and compliance officers coordinating cross‑industry data exchange
- Software developers building middleware and readers that interpret AIDC data structures
Typical uses include serialized inventory tracking, transport unit labeling, returnable asset management, and interoperability planning between optical and RFID systems.
