biometric scanning
Biometric scanning is a technology that uses unique physical characteristics to identify individuals. Common traits used in this process include fingerprints, facial recognition, iris patterns, and voice recognition. These features are measured and converted into digital data, which can then be compared to stored information for verification.
This method is widely used for security purposes, such as unlocking smartphones or accessing secure facilities. By relying on biological traits, biometric scanning offers a more secure alternative to traditional passwords or PINs, as these traits are difficult to replicate or steal.
