  • Patent number: 5327485
    Abstract: Playslip booklets are printed with bar code and numeric identification plus individual ticket identification numbers on each playslip. At purchase, the booklet is authorized for play through the telephone lottery computer, which provides a PIN for the booklet. To play, the bettor calls the telephone lottery computer and provides the booklet identification number and the PIN. The computer uses interactive voice capabilities to guide the player through play entry. For each lottery play, the bettor provides a playslip number. The selected lottery game wager numbers/symbols are verified by the player and may be recorded on the playslip. The telephone lottery computer returns a transaction number to be written on each ticket played to serve as a hard copy identification/verification of the transaction. The tickets then serve as the claim tickets required to collect a prize.
