These reusable digital Polaroids are a clever way to cover a fridge in memories

You can update this photo as often as you want. I love when my friends have their fridges covered in Polaroids. It’s often a visual crash course of what’s been going on in their lives chronicling recent adventures, get-togethers, and other fun moments.

Changing the photo the Snap displays takes about 25 to 30 seconds. While the actual image transfer is a 10-second process, the rest of the time is used to refresh the Snap’s E Ink screen. Unlike devices such as the Kindle Colorsoft that use a black and white e-paper screen overlaid with a color filter so screen refreshes happen almost instantly, the Snap uses e-paper with multiple color pigments that take much longer to refresh. The results look better, but you’ll have to wait a little longer for them. The process of updating the Snap with a new image using NFC is easy once you master it, but it can take a few attempts to get t
