In a card reader for use with a card carrying indicia readable in the form of a binary code at preselected locations thereon, and including means providing a slot for receiving a card and means positioned at preselected locations adjacent said slot and responsive to indicia on a card inserted into said slot for providing a binary coded signal as a function of such indicia, the improvement comprising decoder means for decoding said binary coded signal to provide a plurality of decoded signals each indicative of a selected value of said binary coded signal, output means for providing a reader output in response to a code signal, and means for connecting any selected number of said plurality of decoded signals to a first input of said output means for providing said code signal such that said reader output signal is at one time selectively responsive to any one or more of said plurality of decoded signals.
