发明名称 LOTTERY TICKET VERIFICATION SYSTEM
摘要 Determination of the authenticity and integrity of lottery tickets is accomplished by using an electronic verification machine to compare data contained in electronic circuits printed on the ticket to document data printed on the ticket. The electronic circuits are printed on the ticket 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 ticket. Data can be represented in the electronic circuits by the electrical signature of the circuit which is measured by the electronic verification machine. 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. 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 ticket data.
