The application concerns intelligent micro-particles for presenting data and machine-readable variable information. The intelligent micro-particle (1) of optional size and shape, is made of a high-temperature resistant, electroplated and/or chemically treated metal and is equipped with diffraction micro-gratings (2) and etched identification data (3) in the form of alphanumeric signs, patterns or bar codes. Furthermore, another thin layer suitable for presenting machine-readable information (11) is deposited on the intelligent micro-particles (1). The micro-particles can be used mainly for the protection of property and objects and serve to exactly indentify them and protect them against falsification. |
