METHOD FOR PROTECTEDLY DEBITING AN ELECTRONIC PAYMENT MEANS
摘要
The invention relates to a method for protected transactions involving a so-called smart card (11) and a terminal (12), such as a cash register. In order to prevent the smart card from simultaneously carrying out transactions with several terminals, the invention provides an authentication value (A) which is used in the data exchange between the smart card (11) and the terminal (12) to uniquely identify subsequent steps (e.g. I, III) of the transaction.
