ABSTRACT:
A credit card carrier includes a pair of flaps foldable upon each other. Each of the flaps carries clip switches adapted for receiving credit cards therein. The clip switches are arranged in parallel interconnection with each other, and in series interconnection between an alarm and a battery. When a credit card is missing from one of the clip switches, the circuit between the battery and the alarm is completed and the alarm is energized. The flap also includes a proximity switch such that interconnection between the battery and the alarm is disabled until the flaps are folded onto each other.
