Your requirement is matching exactly with the projects I am experienced into.
I have experience in Biometric project for 'Building security' part of that project was Hand key geometry reading device, fingerprint device etc, by reading the information of employee presence in office by entrance/exit using the device is stored in host and shown in GUI or an attendance report is generated month end.
I can do it easily, but I need device from your side, its manufacturer document etc if any, hope that's not a big issue, device can be sent by courier easily.
Apart from this you can initiate other innovative future projects, that you expect from machines to be done automatically with software. My programming, microcontroller, embedded hardware, electronic skills will always be there.
Thanks!
