Many people may think that the application of RFID is complicated, but in fact the basic working principle of RFID technology is not complicated: After the tag enters the magnetic field, it receives the radio frequency signal from the reader, and uses the energy obtained by the induced current to send out the product stored in the chip. Information (Passive Tag, passive tag or passive tag), or the tag actively sends a signal of a certain frequency (Active Tag or Passive RFID Tags), the reader reads the information and decodes it, then sends it to the central information system for processing Related data processing.

The current RFID products on the market are products that comply with international standards and have reliable security encryption mechanisms. Because of this, the second-generation resident ID cards and subsequent bank cards in our country all use this technology.

Each label has unique identification information. The label is bound to the product information during the production process, and the label uniquely represents the corresponding product in the subsequent circulation and use process. Whether it is pre-sale, in-sale, or after-sale, as long as the user wants to verify, they can use a very simple way to verify it. With the popularity of NFC mobile phones, the user's own mobile phone will be the simplest and most reliable device for authenticity verification.

General label storage time can reach several years, more than ten years, or even decades. Such a storage period is sufficient for most products.General label storage time can reach several years, more than ten years, or even decades. Such a storage period is sufficient for most products.

In order to consider the security of information, the application of RFID in anti-counterfeiting generally uses 13.56M frequency band tags. RFID tags cooperate with a unified distributed platform, which constitutes a whole-process product anti-counterfeiting system.

Moreover, for users, the characteristics and cost-effectiveness of RFID have natural advantages. The operating frequency is 13.56MHz, and the wavelength of this frequency is about 22m. Except for metal materials, the wavelength of this frequency can pass through most materials, but it tends to reduce the reading distance. The label needs to be more than 4mm away from the metal, and its anti-metal effect is relatively good in several frequency bands. This frequency band is recognized worldwide and there are no special restrictions. The sensor is generally in the form of an electronic tag. Although the magnetic field area of this frequency drops quickly, it can produce a relatively uniform read and write area. The system has anti-collision characteristics and can read multiple electronic tags at the same time. Some data information can be written into the label. The data transmission rate is faster than the low frequency, and the price is not very expensive.

In general, RFID plays an irreplaceable role in our lives, ranging from bus cards, access control cards, and ID cards. It can be regarded as a very important step in the development of modern science and technology civilization, as far as the Internet of Things and asset equipment management.
