Back in 2020, we wrote about Waveshare’s Batteryless NFC e-paper display, which can work without a battery and draws power and data from an NFC-enabled smartphone or the company’s ST25R3911B NFC board. Waveshare has now released a V2 version of this display with a new and improved NFC chip, a “fast flashing method”, and enhanced contrast. The new batteryless, 7.5-inch NFC-powered e-paper display features an 800×480 resolution and updates via an NFC-enabled smartphone or reader. It offers a 170° viewing angle and comes in a durable ABS plastic shell. The ST25R3911B NFC board allows updates via USB, SD card, or serial port, with an optional password lock. However, precise NFC positioning is required for updates.

These features make it ideal for shelf labels, equipment tags, and other applications.

The iOS application provides similar functionality for Apple devices. Users can customize displayed content with built-in image effects, including grayscale, block patterns, sketches, and more.
