Unfortunately, the level of detail for scanning fingerprints cannot be achieved with a regular scanner, and it seems to me that you may need to rewrite a part of the os. If you go to www.popsci.com and search fingerprint scanner there are many results, and I recall an artical about controlling a of via fingerprint scanner. Hope I helped!

Just Googling around you can see that and average fingerprint scanner does around 500 DPI, and most scanners sold in the last several years go much higher than that, so the problem isn't the resolution.

However one important difference is that it fingerprint scanners are deigned to be highly sensitive to the distance from the sensor/glass, (so they can read ridges and troughs well) whereas scanners actually try to compensate for these minor variations.

But if you can scan the whole hand you don't need to scan the fingerprint. Several security systems use the overall shape of the palm and fingers as biometric input, since they, like fingerprints, vary between people, and that can easily be read by any consumer grade scanner.

So yes, you can get good biometric data from a scanner. The problem is the software. Recognizing fingerprints, etc is complex and the companies who do it like to keep the methods secret. I don't know of any easy to sue software that can do exactly what you ask.

However, if you have a web cam you can use facial recognition as your login using software such as KeyLemon.

(I suppose you could maybe hook it up to your scanner and scan your face too, but it'd be slow and don't look directly into your scanner bulb.)
