Okay kiddo, do you know what the iris is? It's the colored part of our eyes - the part that can be blue, green, brown, and so on.
Now, when we go to different countries, we need to show some important documents to prove who we are and why we want to enter that country. One of these documents is called a passport.
But sometimes, just showing a passport is not enough to make sure that the person is really who they say they are. That's where the iris recognition system comes in.
The iris recognition system is a kind of technology that can look at the iris of a person's eye and compare it to other records to confirm that they are who they say they are.
For example, when someone wants to enter a country, they might go up to a machine that has a special camera that takes a picture of their eyes. Then, the iris recognition system will compare the picture of the person's eyes to a whole database of other pictures of people's eyes.
If the iris recognition system can find a match, that means the person is who they say they are and they can go into the country. Otherwise, if there's no match, it might mean that the person is lying or there was a mistake, and they might not be allowed in.
So, the iris recognition immigration system is just a way for countries to check to make sure that people aren't trying to come into the country under fake names or fake passports. It's like a super-smart eye scanner that helps protect the country and make sure that everyone who goes in is really who they say they are.
