A method of providing identification of an individual, said method comprising: maintaining a database of identification data each including at least one type of non-invasively determinable biometric attribute capable of distinguishing respective individuals, some of the individuals being restricted individuals, to enable identification of an individual by means of the identification data; providing each of said identification data with a unique description; providing identification means for carriage by each said individual and containing the unique description; providing a receiving station in communication with said database, the receiving station determining at least one non-invasively determinable biometric attribute of said individual of a type stored by said database, reading the unique description contained in the identification means carried by said individual, accessing the database to determine the identification data corresponding to the unique description, comparing the attribute determined by the receiving station with the corresponding attribute included in said identification data on said database, and interrupting the progress of the individual if a sufficient correlation between the attribute determined by the receiving station and the attribute on said database is not found; wherein said unique description is selected and encrypted so that it cannot yield said identification data by unauthorized processing or de-encryption thereby to render the identification means of no value to a person other than the person to whom the identification means is issued, and wherein said identification means further includes validation means arranged to detect tampering with the unique description for outputting a validation signal indicative of whether there has been tampering, and a transponder for transmitting the unique encrypted description and the validation signal, and wherein said receiving station is adapted to trigger the transponder to transmit the unique encrypted description and said validation signal, and to flag a failure to verify by said validation means so as to interrupt the progress of the individual.
