TapInk - NFC E-Paper writer

Create and send custom labels, QR codes, and photo graphics to NFC-powered e-paper displays with a tap.

TapInk turns your iPhone into a simple writer for Waveshare NFC-powered e-paper displays.

Design crisp black-and-white labels, choose icons or QR codes, add styled text and borders, save reusable layouts, or send photos with dithering. When you’re ready, hold your iPhone near the display and TapInk transfers the image over NFC.

Features:

• Create custom e-paper labels
• Add icons, photos, QR codes, text, and borders
• Save and reuse label designs
• Preview black-and-white output before sending
• Choose plain or dithered rendering
• Supports multiple Waveshare NFC e-paper display sizes

TapInk is built for NFC-powered e-paper displays that draw power from your iPhone during transfer. No battery on the display side required.
