The card identifying unit deciphers card property information stored in a card and determines whether the card is valid. The database management unit determines final card property information based on the card property information deciphered by the card identifying unit and property change information stored in the database management unit. The authorization processing unit calculates charges and processes card transactions based on the final card property information generated by the database management unit. The database management unit generates identification numbers sequentially assigned from a predetermined number with respect to respective card numbers corresponding to the property change information, stores the identification number and the property change information corresponding to the identification numbers, and determines the final card property information corresponding to the card property information based on the stored property change information. ## Claims ### Claim 1 A card authorization terminal system comprising: a card identifying unit to decipher card property information stored in a card and determining whether the card is valid;
