How RFID (Radio Frequency Identification) Technology works has been explained. So, in this video, what is RFID, how RFID works, What are tags, What are the Different types of tags and its frequencies have been explained. What is RFID? RFID is technology which works on radio frequency and it is used for the auto-identification to track different objects. An RFID system primarily consists of two parts from a hardware perspective. 1) RFID Readers/ RFID Antennas 2) RFID Tags RFID tags: Now, three different kinds of RFID tags are commercially available. 1) Passive tags 2) Active tags 3) Semi-passive tags Operating Frequency: This RFID system is mainly operated in three frequency bands (Although others do exist) 1) LF: Low-Frequency band 2) HF: High-Frequency band 3) UHF: Ultra High-Frequency band
