ABSTRACT:
The present invention relates to a method and system for comfortably operating chipcard applications in a chipcard application system. It is proposed to define at least one trusted terminal device (12) in a trusted environment for a Chipcard (10) in use with which the card holder verification (CHV) dialogue is suppressed and the CHV operation is performed in the system hidden from the user. Either, the trusted terminal ID is stored on the chip of the chipcard, or, the Chipcard ID (22) is stored on a trusted terminal together with the PIN (Personal Identification Number) of the card holder. Such an association can help to suppress the CHV dialogue in a trusted environment.
