Description
The RFID module is a highly engaging wireless communication component designed to read and write data to compatible contactless smart cards and key fobs using radio-frequency waves. Commonly communicating via the SPI protocol, it interfaces smoothly with microcontrollers like the Arduino UNO and Magic Board. In a STEM curriculum, this module is an excellent practical tool for introducing students to data encryption, unique ID verification, and wireless security concepts. It is universally popular for building hands-on projects such as smart door locks, automated attendance systems, and personalised access control mechanisms.
