Cordova Barcode Scanner

If you need multi-platform barcode scanning, you can try the Xamarin SDK from LEADTOOLS:

https://www.leadtools.com/sdk/xamarin

The code to perform barcode recognition looks like this:

var imageForRecognition = _rasterImage.Clone();

BarcodeData[] barcodesFound;

OneDBarcodeReadOptions oneDReadOptions = _engine.Reader.GetDefaultOptions(BarcodeSymbology.UPCA).Clone() as OneDBarcodeReadOptions;

var symbologiesToLookFor = new List();

BarcodeSymbology[] oneDSymbologies = { BarcodeSymbology.EAN13, BarcodeSymbology.EAN8, BarcodeSymbology.UPCA, BarcodeSymbology.Code3Of9, BarcodeSymbology.Code128, BarcodeSymbology.USPS4State }; //Dozens more are supported

BarcodeSymbology[] allSymbologies = _engine.Reader.GetAvailableSymbologies();

symbologiesToLookFor.AddRange(oneDSymbologies);

BarcodeReadOptions[] readOptions = { oneDReadOptions };

barcodesFound = _engine.Reader.ReadBarcodes(imageForRecognition, LeadRect.Empty, 0, symbologiesToLookFor.ToArray(), readOptions);

return barcodesFound;

Another way to implement barcode scanning from any platform is to use the barcode web services:
