Activities

Technology for real-time access control is widely used in many situations. 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.

ECMA-412 “Framework for distributed real-time Access systems” was developed to define a common module architecture and the message exchanges between each module common to various services such as cloud computing and virtualization. ISO/IEC published ECMA-412 as ISO/IEC 20933 in May 2016. The 2nd edition of ECMA-412 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 2nd edition was also published as a revised edition of ISO/IEC 20933.

ECMA-417 specifies the architecture of a distributed real-time access system, i.e., the layered concept of the system, the functions of each layer, and the interfaces. Additionally, the 3rd edition introduced Central Bank Digital Currency (CBDC) and Vaccine Passport as additional examples of complex authentication.

ECMA-417 1st edition was published in December 2018, the second edition in June 2019, and the third edition in August 2021. ECMA-417 was also published as ISO/IEC 24643 in December 2020.

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. TC51 is also studying various use cases that would benefit from a distributed real-time and secure access system.

TC51-TG1 studies NFC (Near Field Communication). TC47 originally developed NFC standards before the NFC topic was transferred to TC51-TG1.
