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)

Cross-platform BarcodeScanner for Cordova / PhoneGap.

This plugin leverages Cordova/PhoneGap's [require/define functionality used for plugins](http://simonmacdonald.blogspot.ca/2012/08/so-you-wanna-write-phonegap-200-android.html).

|

Note: the Android source for this project includes an Android Library Project.
