I made a copy of the original BarcodeScannerWP8 to try to make it runnable on WP7.

BarcodeScannerWP7/8

Cordova/PhoneGap plugin to enable barcode scanning on Windows Phone 8 using the device's camera.

• The plugin uses the native library ZXing.Net to decode the barcodes.

• The look and feel of the barcode scanner view is consistent with the PhoneGap Build Android/iOS barcode scanner plugin

Licence

MIT

Installation

Using CLI:

• cordova plugin add org.bloxlab.barcodescanner (or substitute org.bloxlab.barcodescanner with https://github.com/bloxlab/BarcodeScannerWP8.git)
• cordova build wp8

Usage

Call the method window.cordova.plugins.barcodeScanner.scan, passing in a success and fail call back. Example:

        function scanBarcode() {
            function onSuccess(result) {
                console.log("Barcode is: " + result.text);
                console.log("Barcode format: " + result.format);
            }

            function onFail(error) {
                console.log(error);
            }

            window.cordova.plugins.barcodeScanner.scan(onSuccess, onFail);
        }

(Device will vibrate after detecting a barcode.)
