RFID cards/tags are based on radio frequency signals. The internal architecture of an RFID card consists of an antenna and a microchip. This 125 kHz RFID tag requires no external power source. RFID tags can transfer data without coming into physical contact with the other device. The coil inside the tag is energized by electromagnetic induction when an RFID reader is brought into its range. This works as a power source to the microchip of the RFID tag. And microchip generates feedback response (unique to each tag) and this response is detected by the RFID reader. Major applications of RFID tags are security systems, industrial systems, toll booths, public transport, attendance systems, etc.
