Radio frequency Identification

  • RFID stands for Radio Frequency Identification. It's a technology which is used to track RFID tags and to capture the data encoded in these tags.
  • It uses radio waves to identify and track tags attached to objects. The tags contain information which is stored electronically. So, it's a kind of wireless communication that uses electromagnetic or electrostatic coupling within the radio frequency to identify an object, animal, or person to which a tag is attached.
  • Today, RFID is used in various industries like automobile, pharmaceuticals, and may even be implanted in livestock and pets to identify them.

How RFID Works ?

  • RFID is an Automatic Identification and Data Capture (AIDC) technology.
  • Using radio waves, it automatically identifies objects, gathers data about them, and enter this data into computer systems with little or no human intervention.
  • An RFID system comprises three basic components : a scanning antenna, a transceiver, and a transponder.
  • The scanning antenna and transceiver are collectively referred to as RFID reader or interrogator. It's a network-connected device that uses radio frequency waves to transmit signals that activate the RFID tag.
  • The transponder is located in the RFID tag itself and comprises an integrated circuit and an antenna.
  • After activation, the tag sends a signal back to the antenna or RFID reader, where it's translated into meaningful data.
  • The data is then transferred through a communication interface to a host computer system, where it's stored in a database and analyzed.
