4.2inch passive NFC powered e-Ink / e-Paper Display

This NFC-powered 4.2-inch e-Paper display operates battery-free and has a resolution of 400x300 pixels. You can simply transfer the images and data you want to display to the e-Paper contactlessly via your smartphone or NFC writing device. The Android app is somewhat difficult to use as the menu navigation is in Chinese. However, sending a text or displaying an image is very easy. Alternatively, you can also use the Waveshare ST25R3911B NFC Development Kit NFC writer.
