Device and method for discriminating a circular plate body such as a coin |
摘要 |
A device and method are set forth for determining the authenticity of a coin or token which includes a housing defining a passageway to pass the coin to be tested. Coils are disposed about the housing to generate magnetic flux lines at the passageway. Detection circuits detect changes in amplitudes of the frequencies generating the flux and signals are created corresponding thereto. These signals are compared at a processor to stored data corresponding to amplitude changes for an authentic coin to determine if the coin is authentic.
