In order to ensure interoperability from a Standards perspective the STA makes use of standards and specifications published by Organisations for Standards, bodies such as CEN and ISO; and other membership bodies such as GSMA, the NFC Forum, etc.
STA has generated a document containing details of the reference documentation used in STA published documents. It is sub-divided by organisation. Note that no particular relevance should be ascribed to the order in which the various bodies appear; each is equally relevant in its own way to the work of STA.
Most STA Documents contain a section on “Normative References” and the latest versions of the references are all included in this STA References Document.
Specific references will continue to be included in STA documents, particularly where the references are dated and have specific relevance to the document they are referenced by. These references may be “cross checked” with the STA Reference Documentation to establish their currency. In other cases where the reference is effectively to the “latest version” of the standard or specification, STA documentation may index to this document.
Note: National Standards and Specifications are not considered in the document, except where they have been translated into other languages by other national standards bodies and hence have a clearly international dimension or where the National Standard is a national implementation of a standard published by international Standards Bodies, such as CEN or ISO. Normally however national standards are the subject of use in specific countries only and are therefore not considered with the STA documentation.

STA considers it is essential that public authorities and users can be confident in the quality of contactless communication between contactless readers and fare media. Certification is the appropriate means to give trust. The STA certification program established by STA consists of a Group of Certification Bodies (STA GCB) bringing together certification bodies authorized to certify compliance of transportation and acceptance media with the CEN technical specification TS 16794 about contactless communication. Extension of the certification scope to ohter technical fields, such as the application layer, may be decided later.
The objective of the STA Group of Certification Bodies is to establish a common approach to conformity certification andt he technical equivalence of certification carried out by the STA Group of Certification Bodies’ members. The members will work collectively to achieve these aims but remain independent certification bodies being reponsible for their own decisions and for the control of their different certification marks. The STA Group of Certification Bodies (STA GCB) works as a platform to ease mutual recognition between the member certification bodies (and the testing laboratories for product testing) and to limit the costs of those agreements. A primary goal of the STA GCB is to ensure that the certification bodies and the associated testing laboratories operate on a common basis.
The main principles of the STA certification program are the following:
- a Group of Certification Bodies (GCB) gathers Certification Bodies (CB) authorized to certify compliance with CEN TS 16794;
- Membership of GCB is open to two categories of CB:
1. a CB accredited according to ISO/IEC 17065 against CEN TS 16794 can be a member of the GCB; 2. a CB complying with a subset of ISO/IEC 17065 can be member of the GCB; it has to submit to an audit.
- Certificates delivered by an ISO/IEC 17065 accredited CB are recognized throughout the EU.
The list of Public Transport Products certified according to STA certification program are available here for CNA/PayCert certified products.
A set of documents gives the framework for this certification program. The Terms of Reference, prepared by the STA CWG and approved by the STA board, defines the Group of Certification Bodies (GCB) and organizes the community of STA CBs. This document indicates:
- the conditions for memberhip for the CB;
- the governance: Board of Management (its initial and current composition);
- the technical structure: CWF and audit manager;
- the CB approval process.
The other documents, elaborated and approved by the CWG, are:
- Testing & Certification Code of Conduct 1.0
- Contactless Interface Certification for Public Transport Products – Certification Procedure 1.0
- Requirements and evaluation methodology for certification bodies 1.2
- The Certification Work Group has finalized new versions of documents for the STA Contactless Interface Certification for Public Transport
The laboratories associated with a CB run “round robin tests” using reference devices and media in order to check that tests realized on the same products by each laboratory lead to similar results thus ensuring consistency across the network of test labs.
