METHOD FOR PROTECTEDLY DEBITING AN ELECTRONIC PAYMENT MEANS |
| 摘要 |
The invention relates to a method for protected transactions involving a socalled 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.
