An identification card (ID card) creation and validation system where the ID card includes at least one unambiguous digital identifier together with additional information stored in predetermined data fields. Upon creation, the ID card is scanned to create and store a composite digital image in a central database on a secured server. On presentation by a user to a human operator-gatekeeper, the ID card is scanned and encoded and the encoded data sent to a central database where it is compared with the stored image information of that ID card to positively identify the user using the unambiguous digital information. If the user is positively identified, the encoded data is compared with the stored data to generate to identify and transmit any anomalies to the gatekeeper, thereby allowing the gatekeeper to exercise independent judgment in allowing or denying admission privileges to the presenter.
