Abstract
A transponder scanner for scanning a passive transponder within a high noise environment has a housing. A ferrite rod is positioned within the housing. A high gauge thin wire is wound about the ferrite rod to form a magnetic coil so that adjacent coils of the magnetic coil are separated by a distance much greater than the diameter of the magnetic wire. A CPU receives the scanned signal corresponding to a preprogrammed code and an in house generated code and maps the preprogrammed code to the in house generated code.
