Secure gaming ticket and validation method for same
摘要:
A secure gaming ticket and validation method for gaming tickets includes storing validation information and ticket identification information in different locations. The stored information is then encoded to create an interim type of data, which is combined with prize information data to create a validation signature. The validation signature determines a win status of gaming ticket.
