# ZBar Barcode Scanner Plugin

This plugin integrates with the [ZBar](http://zbar.sourceforge.net/) library,
exposing a JavaScript interface for scanning barcodes (QR, 2D, etc).

## API

- **onFailure**: function (s) {...} _Callback for cancelled scan or error._

Return:

- success('scanned bar code') _Successful scan with value of scanned code_
- error('cancelled') _If user cancelled the scan (with back button etc)_
