My friend was given a 2nd year project of building a biometric class attendance system,that was to take finger print of each student taking a particular unit as a method of ensuring the student attends at least 80% of the classes.i will be assisting him in the project and we will be using PHP as our development language,now my question was.is their a way of linking a php application with a biometric finger print scanner,and if so how or where can we find the information to guide us on how to do so

It depends more on the capabilities of the biometric finger print scanner. If it can send HTTP request to a domain/IP address then it can communicate with PHP. If you are running the webserver/PHP on scanning station then PHP could read a port or execute a program that reads a port.

@Christopher,thanks for your reply ,the app will be running on a fixed station(only one computer),aleast you gave me an idea of where to start on,because i didn't know about serial ports support in php

..... for anyone who didn't know about this too and want to learn on how to make your php talk to other devices i think this a good place to start

If there is not a PHP library to connect to whatever device you are using, you can also execute a program on the computer using PHP -- sending it parameters and getting back its output. See exec() and related functions.
