How to Implement Barcode Scanner in PowerApps

We can scan a barcode in PowerApps using a barcode scanner or the camera of a mobile device. Here are the steps to do it:

  1. Insert a Barcode scanner control on your screen from the "Insert" menu under "Media".
  2. Select the control and set its properties such as 'OnScan', 'OnScanError', etc.
  3. Preview the app in the PowerApps Studio and open the screen with the barcode scanner control.
  4. Point the barcode scanner or camera at a barcode to scan it.
  5. The scanned data will be displayed in the control and can be used for further processing.

If you want to use a mobile device's camera to scan a barcode, you can use the Camera control in PowerApps to capture an image of the barcode and then use a barcode scanner API to read the barcode data from the image.

Here are the steps to do it:

  1. Insert a Camera control on your screen from the "Insert" menu under "Media".
  2. Select the control and set its properties such as 'OnSelect', 'OnStreamStart', etc.
  3. Create a button or other control to trigger the camera control to capture an image.
  4. In the 'OnSelect' property of the button, set the formula to capture an image from the camera control.
  5. Pass the captured image to a barcode scanner API to read the barcode data from the image.
  6. Use the barcode data for further processing.

There are several third-party barcode scanner APIs available that you can use in PowerApps, such as the Google Vision API or the ZXing library.

  1. Google Vision API: This is a cloud-based API provided by Google that can recognize a variety of barcode formats, including QR codes, EAN, and UPC barcodes. It is available through the Google Cloud Platform and requires an API key to use.

  2. ZXing library: This open-source barcode scanning library can be used in PowerApps. It supports various barcode formats, including QR codes, EAN, and UPC barcodes. It can be integrated with PowerApps using the Barcode Scanner control and a custom connector.

  3. Dynamsoft Barcode Reader SDK: This commercial barcode scanning SDK can be used in PowerApps. It supports various barcode formats, including QR codes, EAN, and UPC barcodes. It can be integrated with PowerApps using a custom connector.

  4. Scandit Barcode Scanner SDK: This is another commercial barcode scanning SDK that can be used in PowerApps. It supports various barcode formats, including QR codes, EAN, and UPC barcodes. It can be integrated with PowerApps using a custom connector.

There may be other barcode scanner APIs and SDKs available as well, so it's a good idea to research and evaluate different options based on your specific needs and requirements.
