RFID smart card working principle
2024-08-28
RFID smart card is a smart card that integrates a radio frequency chip and an antenna, and its working principle is based on radio frequency communication technology. The smart card is equipped with an RFID chip, which is embedded with a unique identification number and can communicate with external devices.
When the RFID smart card is close to the reader, the reader will send a radio frequency signal to the smart card. The antenna in the smart card will generate energy after receiving the signal and activate the circuit inside the chip. The chip reads the data it stores and sends it back to the reader via a radio frequency signal.
After receiving the radio frequency signal, the reader parses the data and performs corresponding processing, such as verifying the identity of the card and reading the information on the card. This two-way data transmission process will realize the interaction between the smart card and the card reader, and complete various functions, such as access control, payment, etc.
The working principle of RFID smart card is based on radio frequency identification technology, which is fast, accurate and convenient. It is widely used in access control systems, public transportation, payment fields, etc. With the progress of science and technology, RFID smart cards will play a more extensive role in the future, bringing more convenience to life.
