What should I do if the application does not work when I need to validate a journey?

If it is not possible for you to validate your journey, identify the cause of the problem.

Mobile phone:

Check that the NFC function of your smartphone is activated.
Try validation again, ensuring that your phone is correctly positioned in front of the validator for the requisite time.
Renew the Seamless application certificate by connecting your smartphone via 3G, 4G or WiFi.
Log in on the Seamless application if you are asked to give your email address and password (it is because you were logged out of the application).
As a last resort, turn your phone off and on again.

iPhone:

Check that the Seamless app is allowed to use the Bluetooth of your iPhone
Check that the Blutooth function of your iPhone is activated.
Try validation again, ensuring that your phone is correctly positioned in front of the validator for the requisite time.
Renew the Seamless application certificate by connecting your smartphone via 3G, 4G or WiFi.
Log in on the Seamless application if you are asked to give your email address and password (it is because you were logged out of the application).
As a last resort, turn your phone off and on again.

Validator terminal:

In this case, validation will be impossible for all Seamless users.
