Heya all programmers, I need your help.

My father is making a php file/page. You basically go to a QR-code with your smartphone and you can registrate there, that you have visited this place. The only problem is, you shouldn't be able to share this link.

I have been trying to make it with link, that you can use only once. My father is trying to do it with cookies.

Can you guys suggest ways to do it too?

You should give more information. Why does he not want you to be able to share the link? Just use Javascript or something

It is a competition, where you need to go to dufferebt places and registrate, that you were there. It should be so, that you cant share this page.
