(The Gist of Science Reporter) Iris Scan
This is another biometric technology used in mobile phones. How much light
reaches the retina on the back of the eyeball is a unique pattern that can be
mathematically defined. Two systems are used to scan the retina: visible
wavelengths and near infrared. The pattern has been recorded and translated into
the data which is then compared against the stored data for the match.
Biometrics on smartphones have increased data security, made payments secure and
increased the pace of processes in various other applications. The technology is
less time consuming and convenient too.
