  • Telecommunications systems for lotteries
    Patent number: 5403999
    Abstract: A lottery system using a public switched network to enter a lottery and to receive an indication of winning while connected on a lottery call. A lottery customer dials a telephone number to enter the lottery. The customer has his eligibility verified by a credit card number or the telephone number of the calling station. The customer is then prompted to speak or key a lottery entry which may be a full number, partial number, or an indication that a lottery comparison number is to be generated by a lottery processor. From the customer's lottery entry, a lottery comparison number is generated. This is compared with a random lottery target number generated by the lottery processor. If the comparison number and target number match, the customer is informed of his winning. Advantageously, lottery customers are quickly notified of their winnings.
