Abstract

The present invention relates to a method and a device for processing coded information stored on an integrated circuit card. A system includes a card reader adapted to receive the integrated circuit card and to read and write data values from an encrypted memory structure of the integrated circuit card. A processor electrically coupled to the card reader includes instructions for executing an algorithm that, in response to insertion of the integrated circuit card into the card reader, extracts information from one or more files stored in the encrypted memory, updates the files based on a current date and information extracted from the files. A display terminal electrically coupled to the processor displays information resulting from the execution of the algorithm. Thus, with the invention, it is possible to alter an operation on the basis of previous operations performed using the integrated circuit card. A method according to the invention includes steps of inserting the integrated circuit card into one of a plurality of card readers and processing the coded information stored thereon in accordance with the algorithm, which can be different for different card readers.
