Abstract

A wireless phone is provided with a GPS receiver and a system which is utilized to report the local position of the wireless phone either prior or during to the time of a telephone placed wager, in which the geographic coordinates of the phone are transmitted to the sports bet for verification that the wager is being placed within the geographic limits of the wagering authority. In one embodiment spoofing of the system is prevented by having the wireless phone report the time since last fix such that an individual within the wagering authority's jurisdiction cannot remove himself from the jurisdiction with the location having been remembered, with the wager taking entity processing as valid only those geographic coordinates having a time since last fix of, for instance, ten minutes. Anything over this pre-determined limit is determined to be an invalid wager. So accurate is GPS that additional anti-spoofing is provided at the wager taking entity in which authorization is withheld if the location reported is identical to a previously reported location. Further anti-spoofing is provided by the phone transmitting its mobile identification number, with authorization for the wager occurring only for a pre-authorized mobile identification number.
