If the card is not accepted, it is necessary to check with your bank whether it is authorized for payment; in any case, it is necessary to purchase a ticket in another way. It is possible to purchase travel tickets for the shuttle at resellers and on the Arriva MyPay app.
If the credit on the card is insufficient, or if the card has been blocked, has expired or deteriorated, the system records an invalid payment and, consequently, does not allow any subsequent use of the service with the same card. To unlock it, you need to register on the travelers portal and carry out the unlocking procedure; if there is sufficient credit available for the balance of previous purchases, it will be possible to use the card again to travel.
