A portable validation unit for an electronic gaming system, particularly a bingo system. The validation unit communicates through a serial data interface with a base station of the gaming system to receive a serial number defining a particular validation unit and corresponding employee, and further receives a validation code defining a particular gaming schedule. As the gaming schedule is played on electronic bingo cards, wins of each game are validated by connecting a validation unit to an electronic card to ensure that the card has a matching validation code stored therein for the current gaming schedule and is indicating a winning sequence of called numbers. If there is no winning indication, then the validation unit sounds one of two audible tunes depending upon whether the validation codes match. In response to a matching validation code and win indication, the validation unit will sound another short recognizable audible tune indicating a win. If a bingo card contains provision for more than one type of win, such as an instant bingo, then different tunes are used to distinguish between win types. There is additionally provided circuitry for transferring a win record stored in a bingo card to the validation unit during the validation process. Another aspect of the validation unit provides for sounding another distinguishable audible tune if the validation unit memory is full instead of transferring a record. At the end of the gaming schedule, the validation unit is adapted to transfer the win records to the base station during an audit process. |
