DataFlex QR and Barcode Scanner

Lesson 1 - Demonstration

In this video we’ll briefly look at a demonstration of the scanner component. For this, we’ll use a mobile device to access our Webapp and scan a barcode.

DEMONSTRATION

So we’re looking at a fairly simple WebApp here. We have 2 buttons that either start or stop our scanner, as well as a form that will contain part of the output our scanner has read, in our case the data inside the barcode
When we start our scanner, we’ll see that it uses our phone’s integrated camera to display a video feed. If your device has multiple cameras, you’ll have the possibility to switch between them
Now let’s scan a simple one-dimensional barcode
The scanner will use the video feed to look for a possible barcode match. And when it finds one, it will output the data contained inside the barcode to the WebForm
We can also do the exact same for a two-dimensional code, in this case a QR code

So that is a quick demonstration of the scanner component. In the next video we’ll look at how to integrate the scanner in your application.
