ISO/IEC JTC 1/SC 31

ISO/IEC JTC 1/SC 31 Automatic identification and data capture techniques is a subcommittee of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) Joint Technical Committee (JTC) 1, and was established in 1996. SC 31 develops and facilitates international standards, technical reports, and technical specifications in the field of automatic identification and data capture techniques. The first Plenary established three working groups (WGs): Data Carriers, Data Content, and Conformance. Subsequent Plenaries established other working groups: RFID, RTLS, Mobile Item Identification and Management, Security and File Management, and Applications.

As of 2017, SC 31 has the following working groups:

· WG 1: Data carrier

· WG 2: Data and Structure

· WG 4: Radio communications

· WG 8: Application of AIDC standards

The international secretariat of ISO/IEC JTC 1/SC 31 is the American National Standards Institute (ANSI) located in the United States

Scope

The scope of ISO/IEC JTC 1/SC 31 is “Standardization of data formats, data syntax, data structures, data encoding, and technologies for the process of automatic identification and data capture and of associated devices utilized in inter-industry applications and international business interchanges and for mobile applications.”

Structure

ISO/IEC JTC 1/SC 31 is made up of, and four active working groups (WGs), each of which carries out specific tasks in standards development within the field of automatic identification and data capture techniques. Working groups can be disbanded if the group’s working area is no longer applicable to standardization needs, or established if new working areas arise. The focus of each working group is described in the group’s terms of reference. Active working groups of ISO/IEC JTC 1/SC 31 are:
