Working of RFID Module

RFID uses electromagnetic fields to transfer data over short distances. The system consists of two main components, a transponder/tag attached to an object to be identified, and a Transceiver also known as interrogator/Reader. The RC522 is a 13.56MHz RFID module that is based on the MFRC522 controller. The module can supports I2C, SPI and UART and normally is shipped with a RFID card and key fob. It is commonly used in attendance systems and other person/object identification applications.

 

  • The reader can read data only form passive tags that operate on 13.56MHz.
  • The tag contains a microchip that stores and processes information, and an antenna to receive and transmit a signal.
  • Time reader module will be waiting for the tag to come into the read range (proximity).
  • A Reader generates an electromagnetic field which causes electrons to move through the tag’s antenna and subsequently power the chip.
  • The powered chip inside the tag then responds by sending its stored information back to the reader in the form of another radio signal.
  • The RF wave is detected and interpreted by the reader which then sends the data out to a computer or microcontroller.
