Security wallet insert for thwarting loss of credit cards

A security wallet insert for thwarting loss of credit cards includes a carrying case which is installed in a foldable wallet, the insert having pockets for holding individual credit cards, and a movable member which must be extended relative to the insert to allow a card to be removed from a pocket, the extended movable member uncovering a “replace credit card” message and making it difficult to close the wallet and thereby impractical to return it to a pocket or purse. A spring activated by removal of a card from a pocket prevents the extended movable member from being returned to a closed non-obstructing position unless the spring is depressed, thus providing a positive reminder that a credit card must be returned to the wallet after the user has made a transaction, and thereby minimizing the probability that the card will be inadvertently left at a place of use.
