Abstract: The invention relates to a system and a method for authenticating a user. A removable storage medium (12) has at least one storage area in which identification data for identifying the removable storage medium (12) are stored, in this storage area or in a further storage area of the removable storage medium (12) data of a digital certificate (14) being stored. Further, a data processing system (18) is provided to which the removable storage medium (12) is connected via a data transfer connection. The identification data and the data of the digital certificate (14) are transferred from the removable storage medium to the data processing system (18). The data processing system (18) processes the identification data and the data of the digital certificate (14) and authenticates the user.

Abstract: In order to maintain self-service terminals (SS terminals), data must be transferred to a data center by means of telecommunication connections. However, in particularly sensitive fields of application, a direct link of SS terminals to external networks or devices is undesirable. Usually, the maintenance personnel must then access the service and diagnostic data locally at the SS terminal and share said data with the help desk personnel in the data center by telephone. In order to be able to transfer the maintenance and diagnostic data directly between the SS terminal and the data center even without directly linking the SS terminal, the data are transferred in a current-free and radio-free data transfer form in the vicinity of the self-service terminal (100) by means of sending and receiving devices (150, 160, 170; MA, CAM, F). This can occur, e.g., by displaying and reading in barcodes (BCs).
