TC51 - Access Systems

Scope - Programme of work

Upcoming meeting

  • the 22nd meeting will be scheduled asap


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. ECMA-412 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.

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. A 2nd Edition of ECMA-412 is in the process of being finalized.
