After a prepatory meeting, the STA decided yesterday (4 Feb 2014) to officialy start a working group called Architecture (of Ticketing Systems). The first aim is to see if the Architecture of Ticketing Systems for Medium Access Devices can be further modularised in such a way that the different existing architectures are harmonised.
The main aim is to reduce global costs of ticketing systems over their whole life span: Initial investment, Maintenance, and Upgrades. But also to facilitate evolution, improving responsiveness to future changes in: use cases, standards, security management, fare rules, and in new technologies such as NFC mobile phones.
So far, ITSO, VDV, Calypso (Europtima) and AFIMB have different apporaches. Both ITSO and VDV have a modular system based on ISO 24014 (the full standard) which is structured to fit the Role Models as they exist in public transport. Calypso, originally not focussed on a strong back-office, has long since recognised the need to accomodate the trend of moving to back-office oriented solutions.
Calypso used the EU project Europtima to fill in that gap. Because the startingpoint for Europtima also were the Use Cases in public transport, the end result is rather similar to what we find in the UK and Germany. The same can be said for the separate work which AFIMB (France) has been performing. In addition it can be stated that Europtima went further and more into the technical details.
The challange is now to see if the four approaches can be 1) harmonised, and 2) improved. One important aspect will be the level of detail (the “granularity”) of the modules. Another aspect is the standardisation and specification of the interfaces between the (black box) modules.
Initially the work will be performed by the STA Full Members and in a later stage the industry will be involved to develop the detailed specifications of the interfaces.

Communications working sub-group (of the STA/GSMA working group)
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.
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:
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.
