TC51 - Access Systems

Scope - Programme of work

Upcoming meetings

  • the 26th meeting will be held on 28 June 2018 in Geneva
  • the 27th meeting will be held on 3 September 2018 in Tokyo (tentative)


Technology for real-time access control is widely used for many situations such as entrance gates of facilities and service access control systems. Membership and settlement services also benefit from real-time access control systems connected via networks and using database information.

Sophisticated cloud, virtualisation, database, networking technology and services and the evolution of authentication technology such as biometrics, NFC, QR codes used in distributed and modular access control systems enable previously underserved users and operators to innovate around new use cases.

In June 2015, TC51 finalized the 1st edition of the ECMA-412 Standard on Access Systems. This 1st edition defines a common module architecture and the message exchanges between each module for various cloud, virtualization and other services. ISO/IEC published ECMA-412 as ISO/IEC 20933 in May 2016.

In June 2017, TC51 finalized the 2nd edition of the ECMA-412 Standard on Access Systems. ECMA-412 defines a framework for distributed real-time Access systems. This 2nd edition introduces new functionalities on performance management mechanisms. Performance management mechanisms allow an Access system to be evaluated for performance by using specific elements and metrics. ECMA-412 was submitted to ISO/IEC for approval under a fast-track procedure to be published as a revised edition of ISO/IEC 20933.

TC51 is currently working on the next phase of the standard and the expectation is that current access systems for particular services can easily expand their services to wider areas and also easily collaborate with various other service systems by keeping interoperability and therefore a standard in mind.
