  • Patent number: 4322612
    Abstract: A single cash deposite may be used for multiple race/multiple day wagering. As a receipt for the deposit, a ticket, having a form upon which a proposed wager may be entered, is issued with a system-generated transaction identification code. The code corresponds to a memory location wherein information concerning credit balance and any outstanding wager is recorded for the transaction. To place a bet, the ticket form is filled in with proposed wager information. The ticket is then inserted into a terminal and read. The memory location corresponding to the code is accessed and any outstanding wager information contained therein is compared to the race results. If same coincide, indicating a winner, the value of the outstanding wager is calculated and added to the stored credit balance.
