The legacy barcode-scanning control, which is obsolete but might be useful for scanning codes in a web browser.
Description
The control shows the camera feed in the app so that users can scan barcodes on all devices. The control is obsolete due to poor performance, and the mobile Barcode scanner control replaces this control.
Key properties
barcode scanner – On a device that has more than one barcode scanner, the numeric ID of the barcode scanner that the app uses.
Scandit is a startup whose goal is to replace bulky, expensive laser barcode scanners with cheap mobile phones. There are SDKs for Android, iOS, Windows, C API/Linux, React Native, Cordova/PhoneGap, Xamarin. There is also Scandit Barcode Scanner SDK for the Web which the WebAssembly version of the SDK. It runs in modern browsers, also on phones. Recently I had a client who wanted to add barcode scanning capabilities to their web app. Their web app was already responsive thanks to Bootstrap but there isn't a convenient way to scan a bar code from mobile Safari or Chrome. This turned out to be fairly trivial thanks to Xamarin and two components in their Component Store.

Accessibility guidelines
Video alternatives
- Consider adding a Label with its Text set to the barcode scanner's Text. Since the barcode scanner does not display the identified barcode value, doing the above makes the scanner accessible to everyone, not just those with visual disabilities.
Screen reader support
- AccessibleLabel must be present.NoteScreen readers will announce when a new barcode has been found. The value won't be announced. As long as the barcode is in view, screen readers will remind the user every five seconds that the same barcode is still being identified.
