This research work is about the concept of automation of library racks while taking books from the rack. It reduces the misalignment of books in a rack. Using fingerprint sensors in an each racks to scan the 2D fingerprint image of the students and it compare with the already existing fingerprints, that are stored in a fingerprint board. The fingerprint sensor (R307) uses Minutiae based matching algorithm for comparing the two 2D images. Fingerprint of the student is matched with the database means, Dc motor will activate with the relay card for opening a door. If the fingerprint of the student is not matched means then the door doesn’t open. Door takes 4 sec to open and it take a 10 sec of interval to take a book from a rack. After that door will automatically closed. Using a Near Field Communication sensor, it has a tag and that tag is placed in a each book with different ID. After the door closed, NFC will activate and it scan the exits book and using Arduino Uno it update to a server with the student id, book name and date of book taken. Student wants to return a book, then directly goes to the respective rack and place the book in a rack using their fingerprint and it will automatically update to the server for returned a book with date.
