hi there, i'am interested in doing this project for my final year and i'm proposing a different method i hope you will help me out in making it happen.
A system where the finger print reader sends the details to a mobile device connected via wireless or any other means asides cable method and this mobile device either a phone or tablet updates the attendance database at a central location with the details obtained from the scanner, rather than having a system where a computer will be connected to the scanner via usb or serial.
i'm proposing this kind of attendance system because of situations where the classrooms are less secured and the lecturer wont be tasked with carrying a laptop to every classroom lecture.
please help with hardware and software details required for this project
What fingerprint reader? That piece of equipment is the critical piece of equipment in your project. Pick that first.
to a mobile device connected via wireless
Connected to what? How much are you willing to spend? How far? How much data? How often? How reliably? Bi-directionally?
There is no one size fits all answer.
and this mobile device either a phone or tablet
You may need to stop waffling and pick a phone or tablet or brick or whatever. You are unlikely to come up with something that can connect to ANY phone, tablet, brick, or whatever.
updates the attendance database at a central location with the details
So, the phone or tablet isn't actually going to do anything. Why have it? Use a Wifi shield and forget the intermediary device.
