# rn-barcode-zxing-scan

A fork of react-native-barcode-zxing-scan, since the original wasn't returning anything and the documentation was wrong. Fixed both here.

The zxing module scanning barcodes in android.

This module abstracts the library zxing-android-embedded, developed by JourneyApps.

## Barcode formats:

- CODE 128
- UPC A
- UPC E
- EAN 8

- ITF
- RSS EXPANDED
- QR CODE
- DATA MATRIX
- PDF 417
