Once you have paid for your fare, you have 30 minutes to add it to your OPUS card.

To do this, you need to:

• Open the Chrono application.

• Click on “Read-Reload OPUS” from the main menu.

• Press “Start reading” (this step is not necessary for Android).

• Press your OPUS card onto the top of your phone (as you did when reading the contents). During this operation, the application will try again to register your fare on your OPUS card.

Once 30 minutes has elapsed, if your fare has not been loaded on your OPUS card, the transaction amount will be automatically refunded to your bank card.
