Bracelet with a monochrome design. Described as “16 color greyscale” on IndieGoGo. Hardly remarkable.
Except — unlimited monochrome designs can be downloaded from your smartphone:
Other interesting claims are that it never needs charging. No of sign a battery in the exploded diagram. Check it out in the IndieGoGo project linked below.
So how does it work, with no battery? IndieGoGo claims that it gets enough power from NFC when a new display is loaded:
“In order to change the displayed picture on the tago arc and transmit enough energy for the device to work, the user has to place his/her smartphone to precisely match both NFC chips”
“NFC induces enough energy during image transfer that the small E Ink display is able to reconstruct the chosen image.”
E Ink displays only consume a miniscule amount of power, & that, only when the display changes. “The image transfer interval is currently 15 seconds, depending on the smartphone device and the image complexity”
It this can be made to work, it will apparently go like this: 15 seconds of NFC will transfer the image, plus charge the capacitors (see the exploded diagram) with enough power to change the display.
Android only for the moment, as Apple has, so far, only enabled NFC for Apple Pay.
