Method of making recoverable smart card transactions, a method of recovering such a transaction, as well as a smart card allowing recoverable transactions

摘要

A method of recovering and thus possibly completing interrupted smart card transactions includes providing a smart card that stores a first and a second pointer, the second pointer being used to indicate an update of the first pointer. In the case of an interruption of a smart card transaction, these pointers are be used to indicate whether a change of a card balance has taken place by the equality of the values of these pointers.
