Abstract: A reader device for reading information stored on a magnetic strip containing a plurality of polarized magnets, each providing a magnetic flux, said reader device including: a magnetoresistive sensor including a plurality of magnetoresistive elements and configured for reading the information stored on the magnetic strip and outputting a read signal; a processing module configured for decoding the read signal and extracting binary data; wherein the read signal includes amplitude information of the magnetic flux; and wherein the processing module is further configured for decoding the read signal using the amplitude information of the read signal is described. Further, an amplitude decoding method for decoding the read signal outputted by the reader device is described.
