ABSTRACT:
The card reader circuit integrated with the reader head structure includes at least one card compatibility network adapted to determine, at the reader head itself, whether or not the card is compatible with the reader head based upon compatibility indicia carried by the card. The circuit also includes a digit readout network cooperable with fixed and movable contacts to read identifying indicia on the card and provide identifying signals at the readout terminal, providing the card is coded such that same is compatible with the reader head.
