RFID may not have been widespread, but it is gradually succeeding

By the time you arrive at the office in the morning, you may have used radio frequency tags (RFID) four times unconsciously: when you insert the car key and turn off the engine anti-theft locking system circuit; when driving through the unmanned toll booth At the time of automatic payment; at the time of using mobile phone to pay for the morning hot milk coffee; at the time of registration to enter the office with ID. RFID may not have been widespread, but it is gradually succeeding.

的玩家rst passive transponders powered by radio frequency input can be traced back to the early 1970s, when they were like most of the various RFID application scenarios today. It is with the gratifying advancement in semiconductor technology today that RFID has really started to take off.

In the commercial market, RFID provides unprecedented opportunities. By providing very detailed data and automating services such as payment and record retention, it can improve work efficiency and improve the user experience. RFID is widely used in various applications, such as livestock identification, retail inventory management, medical records management, electronic non-stop charging, electronic passports, and more recent mobile phones, which will be important promoters of specific RFID technologies.

The market for RFID tags (the identity part of RFID) is growing rapidly and is expected to accelerate. It is predicted that the number of passive RFID tags will increase from less than 3 billion in 2011 to about 250 billion by 2021.

Although RFID applications are usually not high-performance, high-speed designs, the complexity of the entire system is very high due to different standards, frequency selection, and the most important application requirements. Each new design brings decisions about safety, range, signal direction, environmental conditions, power consumption, memory requirements, and interface design. However, once the system architecture is considered mature, the numerous design tools and development kits mainly provided by semiconductor companies can help our project succeed.
