How do you show evidence of a visit to a library?

I have to show evidence of a visit to a library for a project im doing for school but im clueless on how to do that can somebody please explain how to show evidence of that
When we scan/swipe your card your name comes up on the screen. Check out a book, and then have the librarian or worker print out your patron record, it will have the library and the date at the top, with your name and the book that you checked out along with it
