This document provides an overview of RFID (radio frequency identification) technology including its components, types of tags, applications, and a survey on potential industries for application. RFID uses radio waves to automatically identify objects through embedded chips that can be read from a distance without direct line-of-sight. Common applications discussed include credit cards, electronic toll collection, logistics/supply chain, and library management. The survey found logistics/supply chain and library management to be areas respondents thought RFID could be applied.
