More Information
Summary:A combination magnetic tag ( 10 ) is described comprising an optical part ( 20 ) and a magnetic part ( 30 ), the optical part including a plurality of optical elements for conveying an optical code and the magnetic part including a plurality of magnetic elements for conveying a magnetic code, the optical and magnetic codes being mutually complementary for verifying authenticity of the tag ( 10 ). Incorporation of both optical and magnetic codes into the tag is of advantage in that they are capable of rendering the tag less susceptible to copying. The tag ( 10 ) is relevant to appropriate to anti-counterfeiting applications.
