The UdS Card serves primarily as a secure access medium to the service systems used in the central administration at Saarland University. It is therefore not used as a storage medium for personal information.

There are 16 sectors on the chip which can be used by the individual background systems. To acess one of them, an individual key is required. Also, they are sealed off from each other. Only the relevant information required for the respective application, such as the electronic wallet or the connection to the library, is stored in each sector. This ensures that no connections can be made between these background systems via the chip card. For example, it is not possible for the Studierendenwerk to access student registration or personnel numbers and thus link the type or amount of purchased items to a particular person.

The terminals and the other hardware components of the chip card system are located in the administration's subnet, which is separated from the public network by a firewall. There is no direct connection between the card management system and the background systems (i.e. personnel administration), except for when a new card is printed. At that moment, only very specific transactions are forwarded; no direct connection is established. If you use time tracking, your clock-in/clock-out times registered at the time recording terminals are anonymized and regularly transmitted to the SAP system, where they are processed.
