This research article published by the International Journal of Advances in Scientific Research and Engineering, Volume 7, Issue 5 May - 2021Radio Frequency Identification (RFID) Systems are becoming very useful in our daily life due to its advantages such as reduction of human error, theft prevention, time consuming reduction, the auto identification of targeted objects, business processes automation etc. RFID systems has been applied in library to manage items and library operations. Different approaches have been adopted in library management system in the East African region unfortunately some challenges including theft, pages removal, non-customer satisfaction, high cost of used system etc. are still persisting. To address these challenges, an RFID based library management and anti-theft system has been developed to East African Community (EAC) library. It focused on the use of Ultra High Frequency (UHF) band which enable readers and tags to transmit and receive data at longrange. The developed system facilitates users to borrowand return library items using RFID modules and enable librarians to monitor, record library activities and prevent no issued item to cross the library entrance or exit.
