E-paper Dope Card

[midwestside]

Does anybody on here have any experience with "e-paper"?

I had seen a photo similar to this one below:

I thought it maybe looked like a smart phone was being used, but it appeared even thinner than the average smart phone.

In reading another related thread on it, it appears to be "e-paper."
Per this website:

What really caught my attention is that it does not use battery power!
It seems like in addition to a dope card that it would have amazing potential for a lot of other applications.
I also don't understand how it interfaces with other devices to change the display.

In what little reading I've done about it, it sounds like there is a push to bring color applications into the mix.

Anyway, I obviously don't know much about it, but thought it was an interesting topic worth starting a thread about.

Looks cool! Never used one myself. I like the idea though!
