is an acronym for Radio Frequency Identification.
The principle is the non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. The application of RFID is very wide, typical applications are animal chip, car chip immobilizer, access control, parking lot control, production line automation, material management.
Generally speaking, RFID technology has the following characteristics:
1. Applicability: RFID technology
relies on electromagnetic waves and does not require physical contact between the two parties. This allows it to establish connections regardless of dust, fog, plastic, paper, wood, and various obstacles, and communicate directly.
2. Efficiency: The reading and writing speed of the RFID system is extremely fast, and a typical RFID transmission process is usually less than 100 milliseconds. High-frequency RFID
readers can even identify and read the content of multiple tags at the same time, which greatly improves the efficiency of information transmission.
3. Uniqueness: Each RFID tag is unique. Through the one-to-one correspondence between RFID tags and products, the subsequent circulation of each product can be clearly tracked.
4. Simplicity: RFID tags have simple structure, high recognition rate and simple reading equipment. Especially as NFC technology is gradually popularized on smartphones, each user's mobile phone will become the simplest RFID reader.
