Apparatus for verifying an identification card; the card having an imaged of an object or other entity to be identified on a first portion, and a coded representation of an encrypted signal comprising a representation of the image on a second portion. The apparatus includes a controller, a scanner for reading the coded representation, a decoder for decoding that representation, a decrypter for decrypting the decoded signal and a display for displaying the representation of the information. In one embodiment the information includes an image of the object or other entity to be recognized and the card may be verified by comparing the displayed representation with the image printed on the card while the card is held in a card holding station adjacent to the display so that the image is visible to an operator. The apparatus also includes a replaceable memory, printer, or communications link for recording at least a portion of this text message. In accordance with another aspect of the disclosure the signal is encrypted using a public key encryption system and an encrypted decryption key is appended to the encrypted message, and is recovered by the apparatus to decrypt the message.
