The system is designed for use at tracks with slot machines or video lottery terminals, as well as those with just pari-mutuel betting. Turning Stone officials said they have been in contact with a number of tracks around the country interested in the new system. Officials declined to discuss costs.Officials said bettors will be attracted to the cashless style of betting, which has been used successfully at the Turning Stone casino for the past five years. Turning Stone, to abide by New York law that bans slot machines, is able to offer slot-like games by offering the debit-card system for its 1,450 machines.Riolo said the system will allow racetracks to monitor bettors over the course of a day or a year. Riolo, a longtime casino industry executive and former Thoroughbred owner, said the upstate New York racetrack he goes to two times a week has no idea who he is or how much he's betting."So if I'm betting a lot, they don't know to buy me a free meal," he said. "This allows a track to really understand your player, to know your player and his needs, and to know the value of that player to you as an operator and to create loyalty."He said the system, which recently had its first order sent to an Indian casino in Washington state, can be designed to work with any track's wagering system.
