Abstract: The present invention provides a card carrier such as a wallet for reducing the occurrence of loss of a card such as a credit card. The card carrier includes an arrangement for receiving a card and for triggering an alarm when (i) the card is missing from the card carrier, and (ii) the card carrier is placed in an enclosure such as one's pocket or purse. The arrangement for receiving a card and for triggering an alarm includes a pocket arrangement normally adapted to receive a card therein, a card sensing mechanism associated with the pocket arrangement for detecting the presence or absence of a card therein, and an enclosure sensing mechanism for sensing when the card carrier is placed in one's pocket, purse, or other enclosure.
