Method of and apparatus for transferring coin/token signature data between coin/token acceptor devices

摘要

The reference frame of production coin acceptors are calibrated with a set of reference objects so that their individual reference frames may be mapped from one to another to facilitate the transfer of coin signature data from one coin acceptor to another. Individual differences due to component variation are transformed out such that the windows of acceptance for each of the coin signature sensor readings may be as tight as possible to achieve both high acceptance of good coins and high security against unwanted coins.
