Biometric scans are technology-based methods used to identify individuals based on unique physical or behavioral traits. Common types of biometric scans include fingerprint recognition, facial recognition, iris scans, and voice recognition. These scans analyze specific characteristics that are difficult to replicate, making them useful for security and identification purposes. Biometric scans are widely used in various applications, such as unlocking smartphones, accessing secure facilities, and verifying identities at airports. By using biometric data, organizations can enhance security and streamline processes, as these scans provide a reliable way to confirm a person's identity without relying on traditional passwords or identification cards.
