An apparatus and method for remote inspection of a smart card or similar apparatus. A smart card (10) includes an antenna (14) and receiver (38) for receiving transmitted messages and a display (22). The smart card responds to a response request message to display a secure output message prompting a user of the smart card to respond to the party originating the message. When a valid response is received a response confirmation message is transmitted to the smart card (10). If a response is not received or is invalid a deactivate command message is transmitted to the smart card (10). If a response request message is not received within a first time period, or if a response confirmation is not received within a second time period after a response request is received, or if an attempt is made to use the card after a response request is received and before a response confirmation is received, the card (10) will deactivate itself. <IMAGE> |
