Don't forget the e-waste aspect... You can recycle paper easily, but several rare earth metals and e-ink all mashed together are much more difficult, and require a lot more energy to produce.

Honestly, this is exactly the kind of overconsumption that got us to where we are. I don't care what someone's favorite emoji is, quite frankly, and I don't think it's worth strip mining the Congo just to do a Neat Thing. Use a printer, do it for the sake of your grandchildren's future.

And then place a few crayons at the venue if you care about the smiley.

It's not just paper, perhaps at least run the numbers? Though I completely agree it's likely more environmentally costly.

My initial thought process evolved from coming back from yet another conference, and tossing yet another lanyard (colorful plastic, metal clips) and plastic covering into the garbage. I have done this probably around 50 times. So think replacing 100-200 of these for an academic, far, far more for con staff, sales vendors, etc.

One of the hurdles you would have to overcome is convincing all of the conferences to go with these reusable e-ink badges.

Let's say all the organizers are convinced...why not use a common, non-electronic badge instead, since you have everyone agreeing to a common standard anyway? Perhaps something simple where the conference organizers can print out a paper slip (recycled paper even!) that you insert so they get some customization.

There is still the main purpose of those things: Verifying people are allowed to enter.

That is (aside from sponsors, who want their logo there) a reason why it looks as it looks and having it somewhat different from event to event.

A shared programmable batch would require scanning them while entering each room, which creates bottlenecks at doors and more effort as each door needs staff and tech (and as soon as you have staff and tech at each door you can also provide all information there, thus the gain of being able to share information into the badge is gone) and you get to privacy issues.

And then half the badges people bring are broken and most participanta didn't ever have one/lost it/forgot it.

I feel like the paper slips solve those problems already, in the same way they are solved today with single-use plastic badges.

The plastic ones can already be forged, switching to paper wouldnt make it any easier as long as you don't publicize what it will look like in advance.

This is the only thing that matters buisiness-wise, its what I'd expect people who frequent HN do routinely, pitch. It doesn't have to be logical, fun, environmentally friendly, it just has to make it to their level of control. I've seen very illogical things become "standard" with little or no questioning for why it is now this way for no other reason than someone was very good at expressing "this is the way it is and should be" (i.e. they where very good at BS).

I'm not putting steaming poo on my badge, it's the concept of customization that's easily shared- "For the social let's all use our lab's logo, and tonight we can use our student org's logo, and tomorrow for the society meetup we could put a picture of the organism we study". Conversation starters (perhaps I do want to put poo on my badge) in what is a social event with many rapidly-changing sub-contexts. Sticker and pin collecting is fun though, so maybe not such a compelling use-case.

Smaller meetings provide markers for name-tags all the time, that's different from the conference-provided ID I'm required to wear in a conference of 6k+ people.
