I would like to add a project to my portfolio that showcases my skills in C#. I would like to somehow implement a feature of biometric security. For this particular project I wouldn't mind interfacing with a fingerprint reader for example. Can anyone make any suggestions what I might be able to design that allows me to demonstrate my competency aswell as maybe something a little innovative at the same time?

Thanks a lot,


OK, you can try voice analysis. All extra equipment what you need is 5 € mike.
I did few experiments on it inspired by movie Golden Eye, but it would take more effort to achieve significant reliability so I gave up. Hope it could help you.
