Subsequently, when the user card is held over the non-contact card reader unit 18 before the elapse of the predetermined time in step S23, the card reading is determined in step S24, the buzzer is sounded in step S24, and the timer is further set in step S26. The user card information read in step S24 and the user card information 124 stored in the user information file 120 are collated to determine whether or not they are unregistered.

  If it is determined in step S27 that the user card information has not been registered, the process proceeds to step S28, the LED of the card reading status indicator lamp 20 blinks in green, and the step before step S29 passes the predetermined time. If the operation of the alert mode setting switch 28 as a registration switch is determined in S30, the process proceeds to step S31, the buzzer is sounded, and the user card information acquired at that time is registered in the user information file 120 as a valid card.

  On the other hand, if the card has already been registered in step S27, the process proceeds to step S32, the LED of the card reading status indicator lamp 20 blinks in red, and in step S34 before the elapse of a predetermined time is determined in step S33. When the switch operation of the warning mode release switch 30 as the deletion switch is determined, the process proceeds to step S35, and a buzzer is sounded to delete the corresponding user card information from the user information file 120.

  According to such a simple card registration process, a user card to be registered or a user card to be deleted is set in a simple card registration mode by holding a switch operation and a master card, and the user card is contactless card reader. By pressing the registration switch or the deletion switch over the unit 18, the user card can be easily registered as a valid card or the already registered user card can be deleted.
