In this library automation system, RFID technology is being used. A microcontroller LPC2148 with an ARM7 structural design and a unique tag number are used in this technology to identify people and books. The database will be accumulated in this computer and will keep a record about the person who has taken the book, which book he is taking, and in the same way the record will be updated when the book is returned. This microcontroller will process the information and send it to the personal computer database. Consumers today are influenced by the most recent technological advancements. Engineering professionals can now use a variety of cutting-edge technology that weren't around only a few years ago. Regardless of the type of industry, engineering services are in high demand right now. These most recent engineering projects innovations both serve to decrease the work and save a significant amount of time. This library automation system uses embedded "C" programming language as its programming. The Flash Magic Application software from Keil is one of the additional tools utilized in the system. The ease of keeping accurate records of books, the ability to identify library users, and cost-effectiveness are all benefits of this library automation system.
