Abstract
Abstract An alarm system that signals when one or more credit cards are absent from a card stack in the case if the system is enabled. In preferred form, a card stack thickness sensor responds to the stack thickness to determine whether all cards are present in the stack. A first signal device (e.g., a buzzer) in a circuit that includes a single sensor switch operated by the card stack thickness sensor informs the case's owner when not all cards are present if the circuit is enables. A second signal device (e.g., one or more of the cards, or a separate flag) that is projectable from and retractable into the case's interior is operated by a circuit enabling switch, this switch being manually controlled for enabling the circuit when the case is to be stored (the second signal device being disabled, i.e., the indicator being retracted into the case, when the circuit is enabled) and for disabling the circuit when one or more cards is intentionally removed from the case for use (the second signal device then being enabled, i.e., the indicator being projected from the case, when the circuit is disabled). The second signal device alerts the case's owner that the circuit has been disabled if that is the fact that the circuit has been disabled if that is the fact in the event the owner tries to inadvertently return the case to a pocket in the owner's clothing or to the owner's purse without first enabling the circuit by retracting the second signal device into the case's interior.
