How does RFID RC522 work?
The RC522 RFID Reader module is designed to create a 13.56MHz electromagnetic field that it uses to communicate with the RFID tags (ISO 14443A standard tags). The reader can communicate with a microcontroller over a 4-pin Serial Peripheral Interface (SPI) with a maximum data rate of 10Mbps.
What is RC522 RFID module?
RC522 is the highly integrated RFID card reader which works on non-contact 13.56mhz communication, is designed by NXP as low power consumption, low cost and compact size read and write chip, is the best choice in the development of smart meters and portable hand-held devices.
Why is my RFID not working?
And there are probably another 20 factors that can affect an RFID reader’s performance but the most common reasons that keep our customer support agents employed are coupling factors, the material density of the tagged item, RFID antenna patterns, antenna cables, RFID tag density, reading speed, noise, and reading …
What is inside RFID card?
An Antenna – This is the foil inside the card surrounding the edges that picks up incoming radio waves and sends that back out again. A Chip – This generates a unique identifier for the individual tag. The Material – This is the form factor such as card or wristband to which the antenna and chip are fixed.
