No, the solution works on the principle of subsequent payment. Unfortunately, this principle is not compatible with the principle of multiple-journeys tickets. Multiple-journeys tickets have to be paid in advance for a certain number of rides.
The check-in/check-out function automatically calculates the best fare for you. This means that at the end of the day, in many cases, you will travel better than with multiple-journeys tickets.
However, if you always travel the same route, it may be cheaper to buy multiple-journey tickets.
You can buy the multiple-journeys tickets under "Tickets".
