This document discusses applications of RFID technology in supply chain problems. It begins with an introduction to RFID technology, describing RFID tags, readers, and antennas. It then compares RFID to barcodes, noting RFID allows reading many tags at once from farther distances without line of sight. The document outlines how RFID can be applied in a supply chain for demand management, order fulfillment, manufacturing flow, reverse logistics, and supplier relationship management. Benefits include speedy and accurate information, enhanced visibility and tracking, improved productivity, quality and reliability, and reduced operating costs. Challenges to RFID adoption are also listed such as high costs, technical issues, security concerns, and privacy regulations.
