Method and device for processing coded information with an IC-card

Abstract

Abstract The procedure provides processing of coded information during payment for goods at a shop, where the customer has an individual smart card identifying himself and the particular terms to which he is entitled. The memory within the card includes a first identification file, called the Member's file, identifying the customer who holds the card. It also includes a second file, called the Points file, and a third file called the Relationship file concerning the business relationship of the card holder with the shop proprietors. A given processing algorithm is carried out using a part of the date of transaction and further information contained within the files, during a purchase transaction. The data is then written into the Points file, and new information is written into the Relationship file. There is also the optional printing of a coupon indicating the results of the transaction.
