An identification information transmission pathway is separated from a
system side to be performed by a mobile authorization means of an owner
of a security module in a wireless way. To this end, the security module
comprises two interfaces, i.e. one for a communication with a terminal
and a further one for wirelessly communicating with the mobile
authorization means. The mobile authorization means supplies
identification information to the security module for an authentication
examination at its part, either stored in the authorization means in a
memory or otherwise generated there, like e.g. via biometric sensors, via
a keyboard or the like. The security module, performing the examination
of the identification information, like e.g. preferably via a zero
knowledge method or a zero knowledge protocol, respectively, only then
indicates a request for an action at the terminal, like e.g. of a money
transfer, when the examination is successful.
