Despite the advancements in fingerprint recognition technology and availability of highly accurate fingerprint readers, a dirty finger or smudge on the scanning surface is enough to disrupt the performance of your scanner. In some less common cases, technical limitations and inefficiencies may be the causes of poor fingerprint capture. However, in most cases, improper use or poor maintenance is the reason for poor scanner performance.
In this blog, we will discuss different fingerprint techniques, how to properly use a fingerprint scanner and keep its performance up to the mark. We will also discuss how you can get a clear fingerprint image.
Fingerprinting has a long history and experts have developed several fingerprinting techniques for capturing, processing and matching human fingerprints. Back when there were no IAFIS systems, and not even computers or scanners, there were manual fingerprinting techniques for the identification of individuals. However, fingerprinting was mostly used in forensics for identification of criminals or for solving crimes.
The digital age of fingerprinting
Ink based acquisition and manual processing of fingerprints has served human identification needs very well and is still a tried and true way to capture fingerprints. However, ink based fingerprinting is slow and does not fit into today’s fast paced digital world. Time taken in capturing and processing fingerprints is horrendously high, which only suits specific applications. Need of faster fingerprint acquisition and processing paved the way to electronic/digital fingerprinting, which has already become the most popular biometric modality and a mainstream method for personal identification.
How accurate is a fingerprint scanner?
It has been long established that each fingerprint is unique and no two fingerprints are the same. Now when we know that fingerprints are unique, we only have to concentrate on the technology part and how to capture, process and match these unique characteristics, so that there are virtually no errors. While keeping error rates to zero is practically impossible due to several reasons, present day fingerprint recognition systems are highly accurate and offer higher levels of tolerance against several environmental factors, which could lead to unreliable results otherwise.
Using a fingerprint scanner properly is as important as choosing the right fingerprint scanner. Investing on a high quality scanner is always a good idea as it will not only perform better but will give better return on investment in the long run. Accuracy of a fingerprint scanner does not depend entirely on the hardware or the underlying algorithm. How you use it and maintain it, are equally important. So next time before you blame your fingerprint scanner for being inefficient or not performing adequately, ask yourself: when was the last time you cleaned it?
