AbstractInformation can be retrieved from lottery tickets and lottery ticket security can be improved by printing electronic circuits or circuit elements on the ticket. Conductive or semiconductive ink can be printed on the ticket by using gravure, relief, planographic, letter press or flexographic methods to form the circuit elements. In one embodiment the circuit elements are printed over play indica and under a scratch-off coating so that they are removed when the ticket is played. An electronic verification machine can then be used to determine which portions of the scratch-off coatings coveting the play indicia have been removed. A second group of circuit elements can also be printed under the play indicia which improves security by blocking light that may be shined through the ticket and by being tested, along with the first group of circuit elements, for integrity by the electronic verification machine. Printing circuit elements on lottery tickets is particularly suitable for probability tickets because it makes it possible to automatically detect which latex play spots coveting the play indica have been removed or tampered with.
