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. But I don’t love the idea of schlepping around a clunky instant camera or paying a premium for instant film with hit-or-miss results. That’s why I’m infatuated with these magnetic digital Polaroids from a small company called VidaBay . They look like instant photos, but use NFC tech and color E Ink screens so you can change the image as often as you want without ever having to charge a battery. At roughly 4mm thick and 2.5 inches in size, the VidaBay NFC E-Paper Fridge Magnet — also known as the Snap — reminds me of Xteink’s tiny X3 e-reader , but it doesn’t have any buttons, ports, or connectors. The Snap is more like a very tiny version of the Aura Ink digital photo frame you can stick to your fridge. The Snap uses the same kind of NFC chip that lets your smartphone double as your credit or debit card. Using an accompanying mobile app images are wirelessly transferred by aligning your smartphone’s NFC antenna to the one located inside the lower left corner of the Snap. 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. …
