Fingerprint readers are a type of biometric security technology that use an individual’s unique fingerprints to identify them. They work by scanning and analyzing the pattern of ridges and valleys on a person’s fingertip. The reader captures an image of the fingerprint and analyzes the unique characteristics such as ridge endings, bifurcations, and other features. This information is then converted into a digital code that is stored in a database or a device’s memory.
When a person wants to access a secure area, computer, or device, they place their finger on the reader, which scans their fingerprint and compares it to the stored digital code. If the fingerprint matches, the system grants access. Fingerprint readers are widely used for security purposes, as they offer a high level of accuracy and are difficult to fake or duplicate.
