## What it is
Magic ePaper is an open-source Flutter mobile app for designing content and transferring it to battery-free NFC ePaper badges. It offers drawing tools, text and emoji input, image editing with ePaper-optimized dithering, NFC read/write with NDEF support, and utilities like QR/barcode generation and ID/price tag creation.

## Use cases
- design content for an NFC ePaper badge
- transfer images to an ePaper display over NFC
- write NDEF data like URLs or vCards to NFC tags
- create employee ID badges or price tags
- dither photos for tri-color e-paper displays
- generate QR codes and barcodes for badges

## When to choose
- you own a compatible NFC ePaper badge and want a free design/transfer app
- you need ePaper-optimized image processing like Floyd–Steinberg or Atkinson dithering
- you want an open-source, self-hostable alternative to vendor badge apps

## When to avoid
- you need to drive ePaper displays connected to a PC or microcontroller rather than via NFC
- your badge hardware is not supported by the app
- you need a web or desktop design tool
