Abstract
Abstract Determination of the authenticity and integrity of various types of documents such as lottery tickets is accomplished by using an electronic verification machine to compare data contained in electronic circuits printed on the document to document data printed on the document. The electronic circuits are printed on the document in conductive or semiconductive ink using, for example the gravure printing process, and the presence or status of the circuits can be used to verify or authenticate the document. Data can be represented in the electronic circuits by the electrical signature of the circuit which is measured by the electronic verification machine. In the case of lottery tickets, a ticket can be validated by having the electronic verification machine determine which play spots have been removed from the ticket and comparing data on the ticket with the removed play spots to determine a play redemption value for the ticket. Document verification or lottery ticket validation can also be accomplished by transmitting signature data from the electronic circuits via the electronic verification machine to a central computer for comparison with document data.
