The individual tickets work like other single tickets and are valid for the zone or zones you choose when you buy the carnet. Don't forget to start a ticket every time you travel.
You can only use one ticket from the carnet at a time and on the travel card, you can only have one carnet at a time.
For those of you with children, for example, you can also buy for others in the app and buy for others in the online store.
We are working on fixing an issue where, unfortunately, the wrong date and time for how long the ticket is valid is displayed on the screen when you read the ticket on board the bus. The date and time in the app are correct. If you use a travel card, you can ask the driver.
