Why does the diya ID program work like this?

Question

Programming

The essence of this application is in Ukraine, and to confirm my identity, it is enough for me to show this program on my phone and my age will be written there. So in supermarkets in this way I prove that I am over 18. But the point is that if I make the same program with the same name and icon and show it to cashiers. And I will write that I am 48 years old. Explain or am I wrong or what? Because the system works like this in supermarkets

Answer 1

If any suspicion arises, you will simply be refused a purchase. Or they will ask you to show your passport as an "identity document".
It is unlikely that they will do anything for a fake application, but for actions performed with the help of a fake - easily.

Answer 2

About wrong about what? Just read the law, I think there will 100% be some kind of pattern to the application at a high level or confirmation, they are not "stupid" either, suddenly the cashiers look not at age, but at some hidden number / register in your phone and later on age)

Answer 3

They've already faked it.
