The science of identifying people, known as biometrics, has advanced quickly in recent years and offers fascinating trends and potential applications in the future. The broad use of facial recognition technology is the next big thing in biometrics. As smartphones and other devices increasingly have high-resolution cameras, facial recognition has emerged as a practical and safe way to confirm identity. Facial recognition technology can be used to improve customer experiences in retail and hospitality settings and to grant secure access to equipment, structures, or systems.
