EInk Gift Card
These cards were made for some friends who are in to electronics. I came across the EInk screens and control boards on Sparkfun, and thought it would be cool to incorporate them into gift cards.
The only challenge here was getting the images I wanted on to the screens. The nice thing about EInk displays is that the image persists after the display is powered down. So once the correct image was on the screen, all that was left was to attach it to the card.
