Radio frequency identification technology can be widely used in many industries and fields, and it must have its "excellence".
In terms of its external form, the carrier of radio frequency identification technology generally has the characteristics of waterproof, anti-magnetic, high temperature resistance, etc., to ensure the stability of radio frequency identification technology in application. As far as its use is concerned, RFID has advantages in real-time updating of data, amount of stored information, service life, work efficiency, and security. Radio frequency identification can more conveniently update existing data under the premise of reducing human, material and financial resources, making work more convenient; radio frequency identification technology stores information based on computers, up to several megabytes, and can store a large amount of information , to ensure the smooth progress of the work; the radio frequency identification technology has a long service life, as long as the staff pays attention to protection when using it, it can be reused; the radio frequency identification technology has changed the inconvenience of information processing in the past, and realized the simultaneous use of multiple targets. The identification greatly improves the work efficiency; and the radio frequency identification is also protected by a password, which is not easy to be forged and has high security. The technology similar to the radio frequency identification technology is the traditional bar code technology. The traditional bar code technology is inferior to the radio frequency identification technology in terms of updating data, storing information, service life, work efficiency, security, etc., and cannot be well adapted to our country. The needs of current social development are also difficult to meet the needs of industries and related fields.
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.
