Will adding multiple Fingerprint IDs for the same finger improve accuracy ? topic

As some people also have noticed, there is plenty of times that the finger print scanner need to read the finger multiple times, I have noticed sometimes it just refuse my right finger, maybe I am too fast, but when I use my left finger ID it works instantly..

Will adding multiple Fingerprint IDs for the same finger improve accuracy ?
Or is it mostly about having the right "technique" ?
Is it a good idea to add 5 more Fingerprints ID for the same finger ?

Does any one have any success with it ?
