Why is an installation step required on first use?

This step is necessary to set up your Android phone and store the tickets (ticket, Navigo pass, etc.) in a secure way. To do this, you need to install an add-on app based on your phone model:

-If you have a Samsung Galaxy phone (list of compatible models on the Samsung website) or a SIM with titles, you will be required to install the contactless Ticket complementary application in order to access the secure element.

-The contactless Ticket app is also required on the Samsung Galaxy Watch.

-If your Android phone does not have a secure element, you will have to install the additional application My Navigo Tickets in order to store your tickets directly. In this case, be careful not to uninstall it or delete its data, as this will result in the loss of your titles.

These apps must be kept in the phone for the operation of the service.
