This document discusses RFID (radio frequency identification) technology, including its components, types of tags, applications, and a survey on potential industries for adoption. It provides an overview of RFID systems consisting of tags, readers, and application software. The main types of tags are passive, semi-passive, and active, which differ in power source and read range. Current applications discussed include credit cards, transportation payment systems, access control, and supply chain/logistics. A survey found the top industries interested in adopting RFID were logistics/supply chain, libraries, and pharmaceutical manufacturing. The document concludes that RFID provides benefits but also has higher costs and standardization issues compared to barcodes.
