ABSTRACT:
A wallet is disclosed which incorporates an electrical alarm circuit for signalling that e.g. a credit card has not been properly returned to its compartment in the wallet. The electrical current is transferred from compartment to compartment, and from the battery and buzzer portion, by means of contact pads and zones which come together when the wallet is closed. The need to conduct electricity through the hinge area is eliminated.
