ABSTRACT:
A device and method for validating a ticket having magnetic ink printed on at least one side of a ticket. The ink is magnetized to create a magnetic signal in the magnetic ink and thereafter a media reader sensor spaced from the ticket is used to verify the existence of a magnetic signal. The magnetic signal is comparable to pre-existing data to determine a match and/or validate tickets having a match. An optical reader can be used to obtain additional data stored in the form of bar codes or patterns on the printed magnetric ink. The optical signal is comparable to pre-existing data to determine a match and/or validate tickets having a match. Preferred comparators for magnetic and optical matching are microprocessors and preferred media reader sensors for magnetic readers are anisotropic magnetoresistive sensors.
