Identification Tag, Object Adapted to Be Identified, and Related Methods, Devices, and Systems

摘要

Disclosed is an object ( 200 ) such as a credit card, bank note, document, label, etc which carries an identification layer ( 103 ) which contains readable information. The identification layer can include randomly distributed conductive/magnetisable particles ( 303 ), semiconductive particle, optically active particles and the like. The identification layer is sandwiched between an upper layer ( 105 ) and lower layer ( 104 ) to form the object. At least some of the particles are exposed along one edge ( 102 ) of the object and can be read by a read head ( 201 ) which moves along the edge.
