  • Publication number: 20020169020
    Abstract: A cashless peripheral device connecting to a gaming system. The gaming system issues a “cash-out” signal when a player quits playing and receives a “cash-in” signal when a player desires to play a game in the gaming system. A stack of continuous unprinted tickets is stored in the interior of the device. A ticket printer prints a coded value, such as a bar code, on a ticket in response to a cash-out signal from the gaming system. A ticket reader reads the amount printed on the ticket. If the printed value corresponds to the value which should have been printed, a ticket-out transport delivers the printed ticket to the player cashing out from the gaming system. When a player inserts the printed ticket into the device a ticket-in transport senses the insertion and the ticket reader reads the coded value from the inserted printed ticket. The ticket reader issues a cash-in signal to the gaming system corresponding to the value read from the coded value on the inserted printed ticket.
