Agent Qian Wanchuan's Patent Abstract - Download the full text link at the bottom of the page - The present invention uses a barcode to identify product authenticity, and relates to a method of inspecting product authenticity in the field of product anti-counterfeiting inspection technology. In view of the shortcomings of existing product anti-counterfeiting technology, a new method was invented that uses magnetic cards or magnetic strips to connect microcomputers and conduct multiple anti-counterfeiting inspections on product authenticity. It is composed of computer software, magnetic cards or magnetic strips, etc. The characteristic is that after the magnetic card or magnetic strip is input into the computer, the merchant's computer can display the product manufacturer's name, factory address and various text information on the display screen through the network. The password is input into the computer, and the manufacturer can give a set of mathematical operation symbols, and Combine any combination of plain codes to form a set of calculation problems. In the field of commodity anti-counterfeiting, it can be widely used especially in the operation of identifying the authenticity of high-end products. Patent sovereignty item - 1. The method of using barcodes to identify product authenticity consists of microcomputer software, magnetic cards (2) or magnetic strips, clear codes (1, 4), etc. Its characteristics are: a) The product is equipped with a magnetic card (2) or Magnetic strip, scratchable identification code (3), and clear code (1, 4); b) According to the magnetic card (1) or magnetic strip, the manufacturer's computer network contains all relevant text information of the products produced by the factory after they leave the factory. , factory address, factory name, legal representative, phone number, date of manufacture, shelf life, trademark, brand, certificate number, product batch number, bar code, user identification code, website, product magnetic card mutual recognition password, product password, various products and Relevant information that is consistent with the instructions; c) The magnetic card (2) or magnetic strip is input through the merchant's computer. The manufacturer's manufacturer's name, address, legal representative, and shelf life of the product are all displayed on the merchant's computer network through the manufacturer's computer network. on the display screen; d) The identification code (3) can be scratched off, and a set of secret numbers can be identified after scratching. After the secret numbers are input into the computer connected by the merchant and the manufacturer, the manufacturer's computer is confirmed to be an authentic product produced by the factory, and the program software Combined with the clear code (1), any set of operation symbols among the combined operation symbols of addition, subtraction, multiplication, division, and square are given, and a mathematical operation problem is formed; e) The clear code (1, 4) is on the magnetic card (2) or magnetic strip of the product The positions corresponding to the secret code (3) are clearly marked with two sets of data barcodes; f) The plain code (1) is any combination of the batch number, and a set of data given by the manufacturer according to the secret code (2) is inserted. Operation symbols form a mathematical operation
