absolutely elegant way of handling something we've done very 'similarly' in the past, but removing the unnecessary friction of long string auth tokens and generation and tracking and all the rest. Absolutely beautifully done! I will indeed create a few physical cards to carry with me to events 🖤

really love how you've worked thru the thought process on this and landed somewhere so functional. Just checking the other comments, and I'm also very pleased you added Gandalf's suggestion; I'll be using that to my preference. Cheers!
