Comment by DougBTX 2 years ago Some variants use NFC power to drive the display update, so no batteries! 4 comments DougBTX Reply jonahss 2 years ago I didn't realize NFC could deliver enough power for that. I'll look into it. AdamTReineke 2 years ago The demos I saw of this were slow, on the order of 10 seconds to get enough power through. eru 2 years ago If you could store that power in a capacitor it might be fine.Basically, only one change every ten seconds is probably workable, as long as you don't have a ten second latency when asking for a change. jonahss 2 years ago aha! So there is a catch. Still worth checking out.
