BTW, do you know, why Bloomberg switched from the old, more comfortable B-Units (as pictured above) to the new black ones, which dont feature a full fingerprint reader any more (instead you have to slide your finger over a smaller sensor)? The old design was way more comfortable, faster and produced less errors in my experience...

The quality of scan in the swipe sensors is actually better than the older area sensors and they also cost less and take up less space on the circuit board. Perhaps the enrollment scan you did was not as good as it could have been and you should re-enroll to capture a better fingerprint.

One of the nice things about the slide scanner is that it doesn't leave a copy of your whole fingerprint on the sensor (in oil residue).

White bunit ;( makes me miss my days there. Always surprised they never sold them, its the best authentication device I've seen.
