This sounds like a KickStarter! I want one!

I'm interested in this thread and what you guys figure out. I'm thinking
about trying to make a key fob sized device that has e-ink and stores all my
"rewards card" barcodes in it. Then you could push a button to cycle
through your 'cards' and have them scanned at checkout. I want this
because I never actually register my cards and give them my address or phone
number and using 503-867-5309 isn't working because the accounts keep
getting deleted (go figure).

Nathan I have a few of the 2.7" ones on hand; they occasionally are in
stock at Arrow for about $14. I could let you have one or two for that.
Price sounds good!
I also have some code for teensy and nrf51822 to draw to them and have
done board layouts with the passives needed to drive them.
Got that board up online anywhere? Oh and how about the display part # (or
something I can use to find a datasheet)?
Would be happy to help if I can. I really like eink screens and wish
they were a bit easier to use.
Cool, thanks!
I was thinking this could be something powered by a coin cell, with a small
microcontroller and hopefully no external memory. Something that could be
taped with double-sided sticky tape, I think there are some low-power AVRs
that can do deep-sleep while still ticking, I don't need precise timing, it
can be +- several/tens of minutes.
