Abstract: A card security device for cards which have coded information on or within the cards has a mechanically closeable and releasably lockable card vault for releasable locking enclosure of cards within the card vault, the card vault releasably lockable by a releasable lock. The lock is releasable by a recognition processor upon recognition of a user's biometric sample by the recognition processor. An incorrect recognition sample by a user, or forcible entry into the card vault either by forced releasing of the vault door or disruption of the vault casing results in a triggering of a destruction device for rendering useless and unrecoverable by disfigurement or destruction by the destruction device of the coded information on the information carrying medium.

Abstract: A card security device for cards which have coded information on or within the cards has a mechanically closeable and releasably lockable card vault for releasable locking enclosure of cards within the card vault, the card vault releasably lockable by a releasable lock. The lock is releasable by a recognition processor upon recognition of a user's behavior pattern by the recognition processor. Repeated use of an incorrect recognition pattern by a user and recognition processor, or forcible entry into the card vault either by forced releasing of the vault door or disruption of the vault casing results in a triggering of a destruction device for rendering useless and unrecoverable by disfigurement or destruction by the destruction device of the coded information on the information carrying medium.
