A Radio Frequency Identification (RFID) module is an electronic device that facilitates wireless data transfer using radio waves for automatic identification and tracking purposes. It comprises three core components: an RFID reader, tags, and software. The reader emits radio frequencies to activate the tag, which contains a microchip with unique identifying data. Once activated, the tag transmits this information back to the reader, enabling real-time asset monitoring, inventory control, access management, and more. 

This contactless technology offers benefits such as speed, accuracy, and the ability to function in challenging environments, radio frequency integrated circuit revolutionizing industries from retail to logistics and healthcare. With advancements like ultra-high frequency (UHF) and passive/active tags, radio frequency chips deliver versatile solutions tailored to various application needs.
