Radio frequency identification (RFID) is an automatic data capture technology that uses radio waves to identify objects or people. RFID systems consist of RFID tags that can be attached to or embedded in objects, RFID readers that can identify and read tags, and an antenna and transceiver to transmit data back and forth. RFID tags contain electronically stored information that can be read from up to several meters away and without needing direct line-of-sight contact or contact with the tag. The technology provides benefits like automatic identification, tracking of assets, and collection of real-time data without human involvement.

21. Conclusion Use of RFID is likely to increase in the near future. At present, it is unclear whether the effects of the use of RFID technology will be evident in broad measures of economic activity like output or productivity growth. As businesses gain experience with RFID, they may be able to redesign business processes to take advantage of the strengths of the technology and the information that flows from its use.
