Trading cards with e-ink displays (2023)

Neat project. As an aside, the following is a great creative starting point insight:

> At one point, I grabbed a stack of iPhones and splayed them out like a hand of cards. I had the idea that, if each phone displayed the image of a card, you could shuffle the deck just by pressing a button, no physical movement necessary.

But it could also lead to funny "tech thinking". For example: "Imagine we could take the messy hassle out of human conception, and monetize it as an app!"

Is that the tree of life printed on the PCBs?

$5 to best all your friends in this hand! $20 to win all night long!

I really hope the Bay Area keeps this attitude, and that other places adopt it if they haven't already:

"I live in the Bay Area. I'm biased, but this place is full of awesome engineers building things and you can just walk up to them and ask them to explain everything about their project and they will."

Edit to add: It reminds me of Jobs calling up Bill Hewlett at his home as a teen and asking him questions, and Hewlett not only answered them but gave him a summer job.

Nice. I've thought of various similar applications (probably because I saw such somewhere). For example conferences require lanyards with passes attached. Most contract with some company to handle all their creation, then also require you (more or less) to use their app to get a schedule, etc. Why not create a generic, re-usable pass (like OP) that attaches to your lanyard, has some basic features at a glance (schedule, your favorite emoji), and could of course be used to track or facilitate flash-gatherings as needed. IIRC defcom did something like this, I'm thinking more generic.

I think scientists I know would snap something like this up so they didn't add to their kilograms of plastic pass/lanyard waste (if conferences can be roped in to adopting them). Level them up with rare editions (conference awardees could be given titanium frames to swap over), etc. and you have a playing-card-esque market for professionals who go to 3-5 conferences a year, and a flashy feature that conferences would like to offer, etc.

Another use- digital cards that can help care practitioners communicate with their audience: "can you hand me the cards the tell me how you feel?" (cards that describe your symptoms). Customize those pictures, icons, graphics on the card as needed, on the fly, per patient type, etc. Think everything from kids bullied at school to medical and law offices where communication can be a barrier.
