Apparently NFC technology is not only convenient for mobile electronic payments, but you can also use it to energize an ultra-low power, bistable E Ink display. A team of researchers
demonstrated how you could use NFC to transfer documents from your handset to a E Ink display with a single tap.

The inclusion of NFC isn't to simply push data to the display. The team, lead by Alanson Sample, have succeeded in wirelessly powering the display through an NFC transaction with an Android phone.
NFC uses inductive coupling to provide power to passive tags. The NFC E-ink display takes advantage of this through its use of a wireless power harvester microchip to store the energy from an NFC transaction in a 0.17mm thick 1mAh battery. This energy is then used to power and update the device's 2.7" display, with enough excess energy captured from the NFC transaction to allow for cycling of images when away from the phone.
