According to 01net, the service will allow users to pay for single journeys, as well as loading season tickets onto their phones. Users can then tap their phones onto a terminal when entering the bus or tram.
Pictures on the CTS Trial sign up page suggest that the service will be available for users of Android devices. The application will seemingly be making use of the SIM as a secure element, thus eliminating Google's Nexus devices from participation. It will also support NFC 'power off mode', allowing users to continue paying for their transport even if their phone's battery is depleted.
Four French mobile phone networks have signed up to offer the service, which is expected to launch fully in June, 2013: Orange, EI Telecom, Bouygues Telecom and SFR.
