RC522 RFID Card Reader Module Kit

RFID module RC522 + keychain + keycard (13.56 MHZ). The RC522 is a highly integrated reader/writer IC for contactless communication at 13.56 MHz. RFID, or Radio Frequency Identification, is a system for transferring data over short distances . It uses short range wireless communication with a reader device and a key device which contains the code to be read by the RFID reader.Often only one of the two devices needs to be powered, while the other is a passive device.Therefore no need to worry about battery life. This allows for easy use in such things as credit cards, key chains, and pet collars. The RFID Module RC522 is your go to module to quickly add RFID feature to your project. This module includes 2 tags to use for, a key card and a key chain tag. This RFID module runs on 13.56MHz. It also includes headers to solder on to connect easily to your Arduino or microcontroller board. This RFID RC522 has an extensive and well written Arduino library that you can find online. RFID is best used for attendance monitoring, logging, equipment and vehicle tracking or counting, hobby door lock projects and many more.
