RFID (Radio Frequency Identification) is an automatic identification technology that uses RF signals to identify and track objects, people, or animals via RFID tags. These tags can be passive, semi-passive, or active, and they require an RFID reader to function, which converts the signals from the tags for data processing. RFID technology has various applications including access control, asset management, mass transit ticketing, and monitoring systems, and it offers benefits such as affordability and portability.

- 4. Our RFID readerOur RFID reader RFID Reader Module, are also called as interrogators. They convert radio waves returned from the RFID tag into a form that can be passed on to Controllers, which can make use of it. RFID tags and readers have to be tuned to the same frequency in order to communicate. RFID systems use many different frequencies, but the most common and widely used & supported by our Reader is 125 KHz.
