Radio frequency identifiers in game tickets
Abstract:
Game ticketing systems and methods provide for the use of radio frequency identifiers (RFIDs). Game tickets such as instant lottery tickets include a substrate having game data and a removable mask covering the game data. A transponder is coupled to the substrate where the transponder stores a ticket RFID that defines a validation code of the game ticket. Game tickets can therefore be dispensed to consumers, validated and tracked using the ticket RFIDs.
