ABSTRACT A document retainer having receptacles is provided and is equipped with clip switch contact sensors positioned in the retainer receptacles. Documents held in the receptacles maintain opposed faces of the clip switch contact sensors in a spaced relationship by being interposed therebetween. When a document is withdrawn, the contact faces spring into engagement, to form a closed circuit thereby energizing an alarm circuit that has audible and inaudible alarms to facilitate indication of the document withdrawal. A resetable timing device is provided to suppress the audible alarm for a period considered sufficient for a card transaction to take place. Preferably, the retainer is in the form of a compact module that can be inserted into a receptacle in a wallet and used while held in the wallet.
