Our idea uses cell phone to check availability of books in a library, reserve a book and to remind the due date.
User friendly, reliable and fast.
This project is developed in .NET as WinFroms using C# as the frontend and MS Sql Server as the back end. The server system has a GSM-modem which receives the sms sent by the registered users.
