Well, as far as I experimented until now, it doesnt look like URU4000 is that bad after all. It just happens for a couple of cases, and I am going to use thumb fingers, because of wider area. I will update futher, hope to do some statistics, just need volunteers and time - in office!
Swiping cleans of the sensor, but is there any other advantage compared to touch? I believe the human errors are more on swipe compared to touch, because one tends to touch the whole area always. Or perhaps the technology is such that the image output is almost same? Other than the URU4000 sensor, does anyone know of another standalone USB reader which has the fprint driver available? Looks like Eikon 2 cannot be a choice for me, because it does on-device-matching. I dont know if other Eikons can be used (300/500 etc). Havent checked with Authentec yet, but I dont think they provide standalone USB readers.
