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

If the application is not launched automatically when you hold your phone in front of the Seamless validator, it is recommended that you:

• Check that the NFC function of your smartphone has been 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.

If it is still not possible to validate your journey:

• Pay for the service using a different means of payment.
• Contact us here.
