barcode-scanner

问题 I am trying to run demo from https://github.com/EddyVerbruggen/nativescript-barcodescanner/tree/master/demo both locally and online at https://play.nativescript.org/?template=play-tsc&id=CB7XFu&v=2 but no luck. On the playground I have added the plugin.

问题 I want to differentiate between (barcode) scanner and keyboard input in an WPF application. What I need is an event which occurs whenever my scanner is providing data.

问题 In my Xamarin.Android app, I want to use ZXing to scan barcode. I want to display the scanner in the view of an activity.

问题 I have a working iOS barcode scanner using the new AVFoundation barcode scanning classes in iOS 7. I can successfully get a string representation of a 1D barcode (for example, a UPC barcode) but I also need to scan two dimensional PDF417 barcodes.

The scanner recognizes the barcode and returns a AVMetadataMachineReadableCodeObject but sending the stringValue message to

问题 I am trying to use a Datalogic barcode scanner (Gryphon 44xx model) on a Mac, from an application (i.e. I am not writing a device driver). Instead of using the scanner's keyboard emulation I'd like to use the special USB HID scanner protocol, called "USB-OEM" mode by Datalogic.
