Intelligent Scan allows you to use your face and eyes to unlock your Samsung Galaxy S9. By default, you may unlock your Galaxy S9 using facial recognition, iris scanning or fingerprint scanning. However, when you turn on Intelligent Scan on Samsung Galaxy S9 smartphones, you use a combination of both iris and face recognition.

How To Set Up Intelligent Scan On Samsung Galaxy S9
Firstly, Open the Settings app to gain access to the intelligent scan feature.
Once complete, register your irises. I recommend doing this step in-doors. The Galaxy S9 may prompt you to remove contacts and glasses, however, this is not completely necessary in the case of contacts.
Make sure to center your eyes in the on-screen circles.
