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

VidaBay's NFC E-Paper Fridge Magnets (called Snaps) are reusable digital Polaroids using E Ink and NFC technology to update photos without batteries. They offer a sustainable alternative to physical instant prints, with a 2.5-inch color E Ink screen and prices ranging from $27.99 to $99.99 for multi-packs. The update process requires precise smartphone alignment due to NFC limitations.
