Biometric access is a security method that uses unique physical traits of individuals to grant or deny entry to a system or location. Common biometric identifiers include fingerprints, facial recognition, and iris scans. This technology ensures that only authorized users can access sensitive information or secure areas, making it a popular choice for businesses and personal devices. By relying on biological characteristics, biometric access systems are often more secure than traditional passwords or keycards, which can be lost or stolen. As technology advances, these systems are becoming more accurate and widely used in various settings, from smartphones to government buildings.
