I had the idea you could use the fingerprint reader as a vertical scroll 
wheel. But it turns out the api is too shallow for that - all the raw 
data processing is done in firmware. The api just lets you scan a 
fingerprint and return a hash type value which can be compared later on 
to other scans.
