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

Digital Polaroids are now a reality, thanks to a new line of NFC-enabled, color E Ink screens that can be magnetically attached to refrigerators, allowing users to easily swap out memories and mementos without the need for physical film or charging. These 2.5-inch, 4mm-thick digital Polaroids can be updated as frequently as desired, using a seamless, button-free interface reminiscent of e-readers. AI-assisted, human-reviewed.

Overview

VidaBay has released the Snap, a 2.5-inch NFC-enabled digital photo magnet that uses a color E Ink screen to display static images on refrigerators and other metal surfaces. Priced at $35.99 (currently discounted to $29.99), the Snap is designed to replicate the aesthetic of physical Polaroids without the ongoing cost of instant film. It requires no charging, thanks to NFC-based power and data transfer, and is intended for users who want to frequently update a curated set of personal photos in a low-maintenance format.

The device measures roughly 4mm thick and resembles a traditional instant photo, complete with a white border. It uses E Ink’s Spectra 3100 screen technology—originally developed for electronic shelf labels in retail environments—which limits its color palette to black, white, red, and yellow. This results in a lo-fi visual output that, while not color-accurate, evokes the nostalgic look of vintage Polaroids.

What it does

The Snap updates images via NFC using a companion mobile app. To change the photo, users align their smartphone’s NFC antenna with the lower left corner of the device. The transfer process takes 25 to 30 seconds: about 10 seconds for data transmission and the remainder for refreshing the E Ink screen. The app allows users to crop, zoom, rotate, and adjust brightness, contrast, and color saturation. It also generates a preview of how the image will appear on the four-color screen, though final results may vary slightly.

The device has no buttons, ports, or built-in lighting, relying entirely on ambient light for visibility. A non-removable plastic cover protects the E Ink panel but introduces glare and limits viewing angles. The Snap comes with a removable screen protector that includes an alignment guide—optimized for iPhones. Android users must determine their device’s NFC antenna location manually, which may require trial and error.

NFC communication requires direct contact between the phone and the Snap; most protective cases, including thin ones, can block the signal. Testing showed that transfers failed with an iPhone 16 Pro in a leather Nomad case and a OnePlus 12 in a silicone case.

Tradeoffs

The Snap’s main advantages are zero battery maintenance and reusable, easily swappable images. However, its color reproduction is inherently limited. Blues and greens are heavily desaturated, rendering them as grayscale or yellowish tones. While this may be a drawback for color fidelity, it contributes to a retro, analog aesthetic that may appeal to fans of vintage photography.

The lack of backlighting means visibility depends on ambient lighting conditions. The plastic cover also degrades image clarity due to reflections. Future revisions without this cover could improve

Getting Digital Fairness Right: EFF's Recommendations for the EU's Digital Fairness Act

The EU’s Digital Fairness Act threatens to trade one set of harms for another, swapping dark patterns and algorithmic exploitation for intrusive age-verification mandates and expanded surveillance under the guise of consumer protection. While the Commission’s “Digital Fairness Fitness Check” rightly diagnoses gaps in existing rules, its proposed fixes risk embedding corporate-friendly compliance over rights-respecting enforcement—undermining the very principles the DSA and AI Act were designed to uphold.

The West keeps asking how much China subsidises its industries. That is the wrong question.

Western policymakers' fixation on China's industrial subsidies obscures a more critical issue: the country's strategic investments in research and development, which have yielded significant advancements in clean energy technologies, such as the widespread adoption of lithium-ion batteries in electric vehicles and the rapid scaling of solar panel manufacturing. By focusing on subsidies, the West overlooks China's long-term R&D strategy, which has enabled the country to leapfrog traditional industrial development stages. This oversight may prove costly for Western industries. AI-assisted, human-reviewed.
