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

These reusable digital Polaroids, called VidaBay NFC E-Paper Fridge Magnets, allow users to easily update photos on their fridge without the need for a physical camera or film. They use NFC technology and E Ink screens, making them a convenient alternative to traditional Polaroids. The devices are available for purchase at various price points, including a single unit for $30.99 and a three-pack for $88.99. To update the photo, users must align their smartphone's NFC antenna with the device's, which can take some trial and error. The process takes around 25-30 seconds, including screen refresh time.
