射频识别技术应用前进

Nowadays, public transportation can be said to have undergone earth-shaking changes. From the past, only with cash, coins, etc., to the current bus card, subway card or even scan code to pay the fare, the current technology makes our life more Convenient. Among them, RFID is indispensable. What exactly is RFID?

RFID, also known as radio frequency identification, identifies and reads and writes specific target data through radio signals, and can identify and read and write data without mechanical contact or a specific complex environment. Today, the RFID technology application that everyone talks about is actually an RFID tag, which already exists in all aspects of our lives.

RFID working method

There are two ways to work. One is to receive the RF signal from the reader when the RFID tag enters the valid recognition range of the reader. The energy obtained by the induced current is used to send the information stored in the chip. The other is The RFID tag actively transmits a signal of a certain frequency, and the reader receives the information and decodes it, and sends it to the central information system for data processing.

RFID is everywhere

RFID technology is widely used in many fields including channel management, data acquisition and identity verification systems, positioning systems, smart campuses, and intelligent transportation.

For example: our common access control, library management, parking management system without charge, ETC system (not charging electronic toll collection system), ID card identification system, consumption management system, social security card, bank card, time and attendance system, mine personnel positioning, Production line automation management, etc...

For example, like the current car through RFID, sensing and other technologies, you can monitor the location of the car in real time, can remind the driver to respond in advance in various emergencies, and can also realize real-time monitoring of vehicle operating status. Including fuel consumption, speed, tire pressure, tire temperature and so on.

in conclusion

It is not only a very important role in the automotive field, but as long as the application of RFID, sensors and other technologies can be very convenient, improve production and living efficiency.
