The captured image is called a live scan. How fingerprint scanning technology worksįingerprint image acquisition is the most important step in an automated fingerprint authentication system, as it assesses the final fingerprint image quality, which has a crucial impact on the overall system performance.The question then is how is this fingerprint assessed? The answer is: using fingerprint sensors that these scanners come fitted with.Ī fingerprint sensor is an electronic device used to capture a digital image of the fingerprint pattern. Nowadays, they are also being used in laptops. During the 2010s, fingerprint scanners became a common feature on mobile phones. As mentioned above, fingerprints are rather unique and hence, they are used to unlock doors and in other security applications where access is controlled and monitored closely. Not only are fingerprints used by police and other authorities to identify individuals, but today’s fingerprint scanning technology has also made it possible for smartphones, laptops and several other gadgets to identify their rightful users.īroadly speaking, fingerprint scanners are security systems of biometrics (the field of study which aims to identify or recognise people based on traits they have). This is why they are used for identification purposes. Human fingerprints are detailed, nearly unique, difficult to change, and remain the same over the life of an individual, making them ideal long-term markers of human identity. Usually, fingerprint records contain impressions from the pad on the last joint of fingers and thumbs, though fingerprint cards also typically record portions of lower joint areas of the fingers. Deliberate impressions of fingerprints can be formed by ink or other substances and passed on to a relatively smooth surface such as a fingerprint card.
They are easily deposited on surfaces like glass or metal or polished stone by the natural secretions of sweat from the eccrine glands that are present in epidermal ridges. So in this blog, we shall look at what fingerprint scanning technology is all about and how we have to come to depend on it mainly thanks to its use in our smartphones and even laptops/ computers.īefore we delve into this subject, let’s start by looking at what is a fingerprint.Ī fingerprint refers to an impression left by the friction ridges of a human finger. At a time when smartphones have become omnipresent, it is indeed interesting to note how fingerprint scanning has come to be an increasingly important feature in many of these phones.
