Biometric scanning is a technology that uses physical characteristics of an individual to identify or verify their identity. Some common examples of biometric scans include fingerprints, iris scans, facial recognition, and voice recognition. These scans are often used as a means of security, as they are unique to each individual and can be difficult to replicate or forge.

 There are several different types of biometric scanners that are used for different purposes. For example, fingerprint scanners are commonly used to unlock smartphones or to gain access to secure facilities. Iris scanners are used for the same purpose, but they scan the unique pattern of an individual's iris to identify them. Facial recognition systems use an individual's facial features to identify them and are often used in security systems or for identifying individuals in photographs. Voice recognition systems use an individual's unique voice to identify them and are often used in voice assistants or for secure telephone systems.

 Biometric scanners have become increasingly popular in recent years due to their convenience and high level of security. However, there are also concerns about the privacy implications of biometric scanning, as it involves the collection and storage of personal data.

Biometrics is a new and upcoming area for age verification. Minor Decliner is continuing to research, benchmark, and implement leading edge techniques that protect privacy and provide the latest technology for robust age verification in the market.
