LIBRARY AUTOMATION USING RFID (ABSTRACT) Radio Frequency Identification (RFID) is a new generation of Auto Identification and Data collection technology which helps to automate business processes and allows identification of large number of tagged objects like books‚ using radio waves. RFID based Library Management system (LMS) would allow fast transaction flow for the library and will prove immediate and long term benefits to library in traceability and security. In this project the we are

pharmaceutical industries. RFID Radio-frequency identification (RFID) is the wireless noncontact use of radio-frequency electromagnetic fields to transfer data‚ for the purposes of automatically identifying and tracking tags attached to objects. Some tags require no battery and are powered and read at short ranges via magnetic fields (electromagnetic induction). Others use a local power source and emit radio waves (electromagnetic radiation at radio frequencies). The tag contains electronically stored
