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 enables it to establish a connection regardless of dust, fog, plastic, paper, wood, and various obstacles, and complete communication directly.
2. High 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. The high-frequency RFID reader can even identify and read the contents 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 the RFID tag and the product, the subsequent circulation of each product can be clearly tracked.
4. Simplicity: The RFID tag has a simple structure, a high recognition rate and simple reading equipment. Especially with the gradual popularity of NFC technology on smart phones, each user's mobile phone will become the simplest RFID reader.
Advantage
Radio frequency identification technology can be widely used in many industries and fields, and it must have its "excellence".
In terms of its external manifestations, the carrier of radio frequency identification technology generally has the characteristics of waterproof, antimagnetic, and high temperature resistance to ensure that the radio frequency identification technology is stable in application. In terms of its use, RFID has advantages in real-time updating of data, storage of information, service life, work efficiency, and safety. Radio frequency identification can update existing data more conveniently under the premise of reducing human, material and financial resources, making work more convenient; radio frequency identification technology stores information based on computers, etc., up to several megabytes, and can store a large amount of information , To ensure the smooth progress of work; radio frequency identification technology has a long service life, as long as the staff pay attention to protection when using it, it can be reused; radio frequency identification technology has changed the inconvenience of information processing in the past, and achieved multiple goals at the same time. Identification greatly improves work efficiency; and radio frequency identification is also equipped with password protection, which is not easy to be forged and has high security. The technology similar to radio frequency identification technology is traditional bar code technology. Traditional bar code technology is inferior to radio frequency identification technology in terms of updating information, storing information, service life, work efficiency, and safety, and cannot adapt well to our country. The current needs of social development are also difficult to meet the needs of industries and related fields.
shortcoming
(1) Insufficient technological maturity. RFID technology has appeared for a short time and is not very mature in technology. Due to the retro-reflective characteristics of UHF RFID electronic tags, it is difficult to apply them to commodities such as metals and liquids.
(2) High cost. Compared with ordinary barcode labels, the price of RFID electronic tags is higher, which is dozens of times that of ordinary barcode labels. If they are used in large quantities, the cost will be too high, which greatly reduces the enthusiasm of the market to use RFID technology.
(3) The security is not strong enough. The security problem faced by RFID technology is mainly manifested in the illegal reading and malicious tampering of RFID electronic tag information.
(4) The technical standards are not uniform.
