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.

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.
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.
It shows a nice layout with 3D-printed holder, pogo-pins, ESP32 Lolin as programmer, with CC2531 RF dongle as the access point.
