My project is an application used in a library to issue and return books using QR code. The primary usage of this app is in college libraries. Using personal smartphones, users can scan the QR code and check out the books which reduce human work and reduces the average time spent in the library. Users can also search for any book in the library and learn basic information rapidly.

The login data and book data is stored in a firebase database. The librarian application involves 3-4 staff users who can manage the flow of books through the app and when a fraud activity takes place they get notified.
