Barcode scanner control (retired) in Power Apps
The legacy control for scanning barcodes, QR codes, and data-matrix codes on an Android, iOS, and Windows device.
Important
The barcode scanner control is retired as it is replaced by the barcode reader control. While the legacy barcode scanner's existing functionality will continue to be supported in future versions of Power Apps, the barcode reader includes the latest improvements and should be used where possible.
Prerequisites
The barcode scanner control is retired and needs to be enabled to show up in the insert pane.
With your app open for editing in Power Apps Studio:
- Open Settings
- Select Upcoming features in the left-hand menu and select the Retired tab
- Turn on the Legacy barcode scanner setting
Description
The control opens a native scanner on an Android, iOS, and Windows device. The scanner automatically detects a barcode, a QR code, or a data-matrix code when in view. The control doesn't support scanning in a web browser.
Note
The barcode scanner control is supported on an Android, iOS, and Windows device. All other platforms will show a warning that some features of the app won't work.

Accessibility guidelines
The same guidelines for the Button control apply to the Barcode scanner control because it's a button that launches the scan.
Visual alternatives
The barcode scanner is a button that doesn't display the scan result. Consider showing the scan result with a Label control. Set the label's Text property to the barcode scanner's Value property. Set the label's Live property to Polite so that screen-reader users are notified of changes. This change makes the scanned value accessible to everyone, irrespective of visual ability.
Users who have visual and motor disabilities might prefer not to point the camera at a barcode. Consider adding another form of input, such as a Text input control, for users to enter barcodes.
