Looks like you need a gateway (not that expensive but too expensive to just hack with those tags at home).

I’d love to find cheap e-ink tags that can just receive a picture over some cheap wireless protocol and display it.

The link was entirely random to show a similar mass produced product, I didn't do much research.

You can search for NFC ones on the same website, they're a few bucks more.

There are also Bluetooth variants which is more friendly to hacking at home (update over the air from farther away) but those look pricier.

    Does anybody here know a Bluetooth (ideally) or NFC one? Preferably with a known protocol that has open source software... at least a known/open protocol to set the displays if not end-to-end open. I have wanted to play with one of these but haven't been able to find one that is easy to hack on.

    I'd really like a $10-20 epaper display that I could update wirelessly on very low power, there are so many fun projects that could be done with that. There are a few dev boards that almost hit that price point but software support is really bad in my experience.
