This document discusses RFID technology, components, applications, and a survey on SME opinions of RFID. It describes RFID as using radio frequencies to electronically identify objects. The basic components are RFID tags/inlays containing chips and antennas, readers/antennas, and software. Tags can be passive, semi-passive, or active. Common applications include credit cards, toll collection, access control, and supply chain/logistics. A survey found SMEs see benefits of RFID in industries like manufacturing, retailing, transportation, and warehousing such as improved efficiency and reduced costs. Further development opportunities exist in medical and library uses.
