BarcodeScanner
|
||||
==============
|
||||
|
||||
Added version that runs with windows mobile devices.
|
||||
To run on those devices, the zxing.net library must be added to the project (Install as nuget packet - more information on http://www.nuget.org/packages/ZXing.Net)
|
||||
|
||||
Windows Phone currently only supports Scaning for codes, feel free to extend it that it can also encode.
|
||||
|
||||
Cross-platform BarcodeScanner for Cordova / PhoneGap.
|
||||
|
||||
Follows the [Cordova Plugin spec](https://github.com/apache/cordova-plugman/blob/master/plugin_spec.md), so that it works with [Plugman](https://github.com/apache/cordova-plugman).
