ABSTRACT:
The present invention describes a device and a method for performing cashless payments between a customer and a dealer. The advantages of the present invention lie in that payments can be performed over the Internet without implementing special payments commands stored in the customer chip card. It is sufficient to use a normal chipcard with a file structure. Such a file structure can be used in different file system cards and does not depend on the chipcard's operating system. Therefore, the inventive method can be used in a variety of chipcards without implementing special payments commands. The protocol is designed such that per payment only three steps of communication are required.
