A common application of biometric security systems is in fingerprint scanning. This technology is widely used in smartphones and security systems, providing a unique and secure method for user authentication. By analyzing the distinctive patterns of a person's fingerprint, these systems enhance security for devices, bank accounts, and physical access controls. Biometric security is preferred over traditional passwords since fingerprints are unique to each individual, making them harder to replicate or forge. The growing adoption of this technology reflects a shift towards more secure and convenient authentication methods.
