THANK “YOU” THE SECURITY FOR LIBRARY Presentation Outline To Educate and Inform You About RFID system How does RFID works Why RFID Agenda Concern Implementation Benefit Conclusion 1. About RFID system Brief History What is RFID system RFID Architecture Key Components Standards Key Agenda Concern for Library Brief History RFID (Radio Frequency Identifier) an Auto-ID data collection system surveillance, using RF waves for Identifying, Tracking and doing Management of material flow. Basic concept behind RFID is same as “Mirror-Sunlight-Reflection theory ” Invented and used from (Early 1940’s) Commercial Operation begun from 1960’s … In 1970s developers, inventors, companies, academic institution and government sectors were actively worked on RFID Most common application were tracked person and objects, identified goods in supply chain, reusable container, high value tools, security, controlling access to building, networks, payment systems and other assets. What is RFID system RFID is an acronym for radio frequency identification. Briefly the RF stand for “radio-frequency” and ID means “identifier” that allows an item, for instance a library book, to be identified, accessed, stored, reprogrammed and communicated by using radio waves A method for controlling inventory Automatically identify objects An AUTO-ID based System Offering Self Check out/in Saving Time and Money Gathering statistics on used Items Minimize Work Stress of Staff Easily Prevent Theft Improve Customer Services And Non-Line-Sight Communication RFID Architecture Tags Reader Gateway Database Database Application User Interface Backend Fig.1. A General Overview of RFID Architecture Scanned As depicted in figure.1 the whole operation are worked under three key phases. Firstly items-tag are scanned by reader; Secondly in backend transmitted data coming through antenna (RF-wave) are being recognized by RFID-based system PC. It acts as a middleware communication gateway am
