"VidaBay's Classic Plus NFC E-Ink Fridge Magnet features low power color E Ink screens that display photos from smartphones without requiring a battery, utilizing NFC technology for updates."
"The E Ink display technology only uses power when changing images, allowing the fridge magnet to maintain a display indefinitely once an image is set."
"The E Ink Spectra 3100 used in VidaBay's magnets is designed for retail use, limiting color reproduction to four particles: black, yellow, red, and white."
E Ink technology has expanded beyond e-readers to include digital photo frames, smartphones, and electronic price tags. VidaBay's Classic Plus NFC E-Ink Fridge Magnet utilizes low power color E Ink screens to display photos from smartphones without needing a battery. These magnets are available globally in various colors for $35.99 each. The E Ink display only consumes power when changing images, relying on NFC from smartphones for updates. However, the color accuracy is limited compared to other E Ink products due to the use of a retail-specific color screen with only four colors.
