France: Strasbourg chooses Calypso

For its mobile transport application U’GO, the Compagnie des Transports Strasbourgeois (CTS) has chosen Calypso.

CTS is the transport operator for the Strasbourg area. With around thirty bus routes and six tram lines, CTS operates the biggest interconnection network in France. In addition to this basic network, CTS offers its customers:

- Self-service bicycle rentals (Vélhop)

- A car-sharing service, in partnership with Autotrement

- Coach service within the department via its subsidiary CTBR

For its mobile transport application - U’GO, CTS has chosen Calypso.

When launching the ticketing service, CTS originally decided to use two technologies, Calypso and a rival product. At the beginning, Calypso was being less used however, the trend has now reversed:

- in terms of security, Calypso offers better assurance against fraud

- and because CTS wishes to develop home reloading, which is cheaper with contact readers, something only possible with Calypso cards, given that they benefit from a double interface (contact and contactless).

In 2014 CTS decided to launch a mobile ticketing service to improve access to public transport, and to simplify the lives of its customers by avoiding queues.

To do so, it developed a mobile application - U’GO, which offers a secure service both for purchasing and validating tickets and allows customers to choose the ticket best suited to their budget. CTS has decided to use Calypso’s Triangle applet, which is easier to implement than other competing solutions and which, due to its interoperable nature, allows for the application to share resources when saved to the SIM. For 2015 in particular, CTS is planning to develop interoperability with SNCF.

U’GO works with all major mobile networks and is compatible with around fifty Android NFC-compatible phones.

To minimise the cost of development and in order to avoid having to update terminals, CTS has developed an original system:

- At the 1300 points of access to public transport there are NFC tags that allow the application to process pre-registered tickets in the form of tokens in the Triangle Cardlet.

- Following purchase, the tickets are loaded onto a back-office application account to ensure the safe-keeping of these tickets in the event of loss or theft of the mobile phone.

The project partners are Ixxi (AMO) and Sopra, who have developed the mobile application and OBS who has provided the TSM (Trusted Service Manager). The Triangle Cardlet is provided by CNA.
