System for article mark and identification, marking method and identification method

Abstract

The invention discloses a commodity mark and identification system, a mark method and an identifying method. Firstly the corresponding bar code label unit and the radio frequency label unit are equipped with the marking commodity, wherein the radio frequency label unit is provided with key pre-wrote by the video information reading and writing unit; when the user identifies the commodity, the bar code reading unit reads the authorization code information in the bar code label unit of the commodity, then the radio frequency information reading and writing unit converts the authorization code information to the corresponding key by the presetting encryption algorithm, and the radio frequency label unit compares the key with the own key, we can read the commodity identification information in the radio frequency unit after the key checking is crossed. The radio frequency identifying technique and the bar code technique is fit for the automatic production, which provides the saving space for the solid information.

Description

technical field [0001] The invention relates to a system for marking and identifying items, a marking method and a identifying method. Background technique [0002] At present, driven by profit, counterfeiters continue to intensify counterfeiting technologies and methods, and even form a professional, group, systematic, and networked production model, which makes users hard to guard against and suffers. At the same time, legal manufacturers and enterprises have also suffered huge losses, and their products and brand images will be seriously damaged. In order to combat counterfeit manufacturers, protect distributors, and improve customer loyalty, companies need a complete product anti-counterfeiting, identification and tracking system. Therefore, the radio frequency identification technology (RFID technology) that appeared in the 1990s was applied to the field of anti-counterfeiting. Because the UID code of its chip is unique in the world, the information is stable, and the ...

Problems solved by technology

This kind of label adds a layer of magnetic material, which increases the thickness of the label by millimeters, and the cost of the label also doubles, making it difficult to apply to delicate small items

In addition, some frequency drift compensation methods are often difficult to work due to many uncertain factors in the single product itself.

[0005] At the same time, most of the RFID tags currently on the market are produced with paper or plastic film as the base material, which gives criminals an opportunity to take advantage of them, because criminals can use certain physical and chemical means to remove the RFID tags attached to the surface of the product. Its integrity is stripped from the sticker and reused
