In this video, RFID (Radio Frequency Identification) Technolgy has been explained. So, in this video, what is RFID, what is inside this RFID system, how RFID works, and application of RFID have been explained. What is RFID? RFID is technology which works on radio frequency and it is used for the auto-identification for the different object.
