I completely agree. Thinking more along the lines of- whether or not something is better may not drive a market, people loved Tamagotchi but vanilla stuffed animals last generations... but Tamagotchi still work for many.

Something that has dirt simple utility (you have a visual que that can be rotated that indicates to staff processing thousands of people an hour that you're payed) without requiring a phone that can do all that and more maybe be generically useful.

If you try to sell something on the basis of "so they didn't add to their kilograms of plastic pass/lanyard waste", the question of whether it actually saves anything is clearly relevant.

I'm also confused why you think receipt that can be rotated is somehow a difference maker, have you ever encountered on that can't be?

Agreed. Just like re-usable plastic bags are now possibly worse than 1-time use unless they themselves are used many times.

This is the concept behind metro bus services in many places I've experienced, the driver glances at the color of your ticket and knows it's nature and whether you can keep riding or not. Don't know if that's a difference maker for conferences.

Looking for "badgers", or a syncronized icon instead of time/date etc., possibly coming at you in many different forms (phone, paper forms, etc) seems like it might be quicker. It might also cut down on people losing their badges (they are more valuable to them) and requiring re-prints ... which happens a lot, this is grasping.
