Card overview

The clearing system CARDS EXCHANGE also enables access to the system for the smart-card holders (travellers). They can view details on the use of their cards (like a statement of a credit card). As the smart cards can be used to store other information besides the electronic wallet, such information is also accessible via the internet interface (e.g. validity of season tickets, the electronic wallet balance, the status of the card blockage).

This access is available pursuant to approval from the card issuer, who permits such access and issues a user name and login password to the card user.
