a fingerprint verification program

we must do the same dear member. can the 8051 see the finger? how can the port pins p2 see the finger? what crystal will you use? and where will the webcam be connected?

im showing you a demo program done by be..recently for that with which i found some warning n errors.
i.e. I can't go with the array data saving operation that should contain by SBUF register here.
