Irises
Use iris recognition as an alternative to entering
passwords in certain apps. You can also use your irises
to verify your identity when logging in to your Samsung
account.
Warning: Some people may have dizziness, seizures,
epileptic seizures or blackouts triggered by light
flashes or patterns, even if they have never had a
seizure or blackout before. Anyone who has had a
seizure, loss of awareness, or other symptom linked to
an epileptic condition, or has a family history of such
symptoms or conditions, should see a doctor before
using the Iris Scanner.
DO NOT stare directly into the infrared iris recognition
LED as prolonged use can cause eye strain. Do not
stare at the iris recognition LED light when your eyes
are less than 20 cm (~8 inches) away from the device,
for best results keep your eyes between 25-35 cm
(~10 14 inches) away for optimum recognition.
Settings
Note: The Iris Scanner is not intended to be used as a
medical device and the biometric data collected and
stored locally by the mechanism is not intended to be
used for any diagnostic, therapeutic, or preventative
purposes. Please follow all instructions for use of this
feature.
For best results, remove eye glasses and sun glasses.
Do not use the Iris Scanner in bright sunlight or areas
with excessive reflected light (for example, by the pool
or seashore). Do not use the Iris Scanner in low light.
Look straight at the device (not up, down or sideways),
and hold your head still for the scan. Tinted contact
lenses and surgically repaired or replaced iris lenses
may interfere with operation of the Iris Scanner. Do not
walk or operate a vehicle while using the Iris Scanner.
