METHOD AND SYSTEM FOR UPDATING A CONTACTLESS SMARTCARD AND A COMPUTER READABLE MEDIUM FOR PERFORMING SAID METHOD

摘要

Method for updating a selected contactless smartcard in a system comprising a plurality of contactless smartcards, a plurality of mobile devices, such as mobile telephones, and a secure server, wherein the secure server is hosted at a network end point and is adapted to communicate, using a wireless communication protocol, with each of the mobile devices of said plurality of mobile devices, and wherein each mobile device is adapted to communicate with an associated contactless smartcard by means of Radio-Frequency Identification (RFID), wherein the contactless smartcard data structure of each contactless smartcard of said plurality of contactless smartcards is provided with a card-transaction log file, comprising a list of transactions relating to said contactless smartcard, each transaction in said card- transaction log file having a unique identifier, and wherein the secure server is provided with a plurality of server-transaction log files, with one server-transaction log file for each of the contactless smartcards in said plurality of contactless smartcards, each server-transaction log file comprising a list of completed transactions and possible pending updates related to the contactless smartcard, the method comprising: - reading the card-transaction log of the selected contactless smartcard to identify an identifier relating to the last completed transaction for that contactless smartcard, - using said identifier to select the server-transaction log file for the selected contactless smartcard on the secure server, - reviewing the server-transaction log file for the selected contactless smartcard to detect any pending updates, and in case a pending update is found, - generating instructions on the secure server relating to said pending update to update the selected contactless smartcard, - forwarding the instructions to said selected contactless smartcard to update said selected contactless smartcard.
