Abstract

The authorization card has one or more storing zones for storing a predetermined information defining the type and/or extent of authorization, for example credit information in case of a credit card, and at least one storing zone for storing variable information associated with the owner of the card. These storing zones are adapted for automatic reading of the fixed and variable information in an automatic reading device. The authorization card has means for generating a coded information to be compared with the variable information. This coded information is manually adjusted on the authorization card by its user and is also adapted for automatic reading by the automatic reading device. Manual adjustment of the coded information is facilitated by a scale provided on the authorization card.
