Abstract
Abstract An authenticator device, e.g. card, of verifiable composition substance and informational content with a system of production and verification. Character uniqueness signals identifying the composition of the device are recorded on the card in an encrypted form combined with statistical data signals representative of information on the card. Testing the card involves freshly sensing the character uniqueness data and entering the statistical data. Such fresh data is then compared with the recorded values after decoding. Favorable comparisons manifest approval and enter the statistical data for processing.
