Abstract
A reader for article identification comprises one or more solenoids configured to generate a magnetic field for locally exciting portions of a marker element carrying at least one data feature as the marker element moves through the magnetic field and for causing the marker element to generate a varying magnetic field; and one or more giant magnetoimpedance (GMI) sensors upstream of the one or more solenoids configured to detect the varying magnetic field and produce output based on the varying magnetic field.
