US 9,805,224 B2 · Magnetic anti-counterfeit label and identification system thereof

Abstract

A magnetic anti-counterfeit label and identification system thereof, wherein the magnetic anti-counterfeit label comprises a substrate, a magnetic ink layer, an opaque layer and a protective coating. The magnetic ink layer covers the substrate. The opaque layer covers the magnetic ink layer in order to visually hide the characters, bar code, and other patterns which are printed using magnetic ink. Additionally the protective coating is composed of a polymer or a metal layer, which covers opaque layer. This identification system comprises a magnetic sensor for sensing the magnitude of the magnetic field emitted by the magnetic anti-counterfeit label, a permanent magnet or an electromagnet for magnetizing the magnetic anti-counterfeit label, a digital processing circuit that is electrically connected to the magnetic sensor, and a frame that is used to hold the magnetic sensor and the digital processing circuit. The digital processing circuit outputs a code corresponding to the magnetic anti-counterfeit label.

Dependent claims

A magnetic anti-counterfeit label, the anti-counterfeit label comprising:

a substrate,
a magnetic ink layer,
an opaque layer and
a protective coating,
wherein the magnetic ink layer covers the substrate and has KV that enables a super-paramagnetic relaxation time thereof to last 5 to 6 hours in an ideal working temperature, the KV being a product of an anisotropic energy density and a particle volume;
wherein a character, bar code, or pattern structure printed using magnetic ink is formed on the magnetic ink layer;
and wherein the character, bar code, or pattern structure has a magnetic property, an optical property, and a physical shape;
wherein the opaque layer covers the magnetic ink layer and is a print structure or a weak ferromagnet that can visually hide the character, bar code, or pattern structure;
wherein the protective coating covers the opaque layer and is composed of a polymer or metal that cannot be magnetized;
and
wherein a total thickness of the opaque layer and the protective coating is less than or equal to an ideal resolution of a MICR character.
