A biometric device is a technology that uses physical or behavioural characteristics to identify and authenticate individuals. These characteristics can include fingerprints, facial recognition, iris scans, voice recognition, and others. Biometric devices are used in a variety of applications, such as security systems, time and attendance tracking, and access control. 

They can be standalone devices or integrated into other systems, such as smartphones or laptops. Biometric devices can be used for identification or for authentication, or both. Identification is the process of determining who a person is, while authentication is the process of verifying that a person is who they claim to be. Some common types of biometric devices include fingerprint scanners, iris scanners, and facial recognition cameras. Saanvika Enterprises sells biometric technology and devices.
