RFID is a simple wireless system, also known as radio frequency identification technology, which refers to a way that can identify specific targets and read and write related data through radio signals, and transmit digital ID and other data between the RFID tag and the reader . It does not require mechanical contact or specific complex environment to complete the identification and reading and writing of data. The application of RFID technology that everyone talks about is actually RFID tags, which now exist in our lives.

The advantage of the RFID radio frequency identification system is the non-contact automatic identification technology, which does not require manual interference during identification. It can penetrate snow, fog, ice, paint, dust and the harsh environment where barcodes cannot be used to read tags, and can also be attached to objects And used to track and manage inventory, assets, personnel, etc. For example, radio frequency tags can be attached to cars, computer equipment, books, mobile phones, etc. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the reading speed is extremely fast, and the operation is quick and convenient.

RFID can scan quickly, and the RFID identifier can identify and read several RFID tags at the same time. RFID reading is not limited by size, and RFID tags can be developed into miniaturization and diversification to be used in different products among.

In the traditional barcode, the carrier usually seen is paper-like, so it is extremely vulnerable to damage and contamination, but RFID stores the data in the chip, so it can avoid contamination and damage, and can be reused . RFID tags can also be added repeatedly, and the data inside can be modified to facilitate the update of information, thereby optimizing the database.

When RFID is covered, it can also penetrate items of various materials, and can carry out penetrating communication. RFID has a large data memory capacity. Since RFID carries electronic information, the data content can be protected by a password, making it difficult to modify the content.

RFID has many uses. Because of its long-distance reading and high storage capacity, it can greatly improve the efficiency of information management, control the amount of information required, and allow it to optimize the demand of the entire supply chain.
