ABSTRACT:
A method and read head for reading MICR characters using magnetoresistive technology. First and second magnetoresistive sensors are printed on a substrate which is supported on a base. The first and second magnetoresistive sensors have a width W and a gap G therebetween, with W and G bearing a relationship to a font of MICR characters to be read. The first and second magnetoresistive sensors are coupled to a full bridge circuit to provide adequate sensitivity to read the MICR characters by the magnetoresistive technology.
