Radio Frequency Identification or RFID technology has been around for decades but in the last few years RFID market size has witnessed tremendous growth. The global RFID market is at 18.45B USD at present which is expected to reach 36.5 B USD by 2030. With advancements in internet technology and wide area networks, RFID now finds applications across various industrial and commercial business domains.
The first use of RFID is said to have been around World War II and then there was the famous US seal, the listening device which was gifted to an American ambassador by a Russian counterpart.
Radio Frequency Identification is a wireless technology that uses an electromagnetic field to transmit and receive information with the help of RFID tags and Readers along with a dedicated software system to store and analyze data.
