We finally have a plan and the name of our application is Guard's Assistant which is an application to be used by security guards to maintain schedules and have their attendance marked and the application is going to be a client server application .
A WCF service is going to be providing data to the application and we are planning to create a web based control center.
The app will be sending information to the server and it'll be sending the GPS location of the guards.
Hope its gonna be a great app.
we'll keep you updated of the progress.
