Send an image

1. Enable NFC on the phone.
2. Open the app and pick a screen model.
3. Tap Send an image, choose an image and optionally apply an effect.
4. Bring the phone's NFC area close to the e-Paper antenna on the back.
5. The app transfers the image and shows progress.

For the best result, use an image close to the screen resolution (800×480 for the 7.5"). The image is converted to monochrome before sending.
