What is RFID Reader and How does it Work?
Radio Frequency Identification (RFID) is a vital communication protocol utilized extensively on the Internet of Things (IoT) and Machine-to-Machine (M2M) applications. The RFID reader, a critical component of this technology, operates based on the principles of electromagnetism. It sends an electromagnetic signal that interacts with an object, and by using an electrostatic coupling, the RFID reader can detect the presence of objects. RFID, and specifically RFID readers, are widely used in businesses and industries, making them very popular. An RFID system typically comprises an RFID reader, an RFID tag, and an RFID antenna. The function of the RFID reader is to extract data from RFID tags, which store crucial user or product information. The role of the RFID antenna, on the other hand, is to facilitate the transmission and reception of information. In this article, we will focus on RFID readers and some of the key facts related to them.
