1. A scanner for use in scanning passive transponders utilizing an LC circuit comprising a housing;
- antenna means for transmitting and receiving a signal including a ferrite rod supported within said housing, a magnetic coil defined by a wire wound about said ferrite rod to form a plurality of coils, the antenna means receiving a preprogrammed ID number from said scanned transponder;
input means for generating a user selected in house ID number;
mapping means for generating an in house ID number in response to said input means and for mapping said preprogrammed ID number to said in house ID number to form a mapped pair;
display means for receiving said in house generated ID number and displaying said in house ID number; and
processing means for processing said in house ID number when data representative of said preprogrammed ID number is received.

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.
