Good Morning!

I created a Unit VIN text column, and now I want to capture the value from a barcode scanner and store it in this column. How can I collect and save the scanned value to the column?

OnScan Property (for Barcode Scanner)

UpdateContext({scannedBarcode: BarcodeScanner.Value})
 

And I made a text column to collect value and

Default Property (for Text Input)

scannedBarcode
 
 

Also, I tried the formula in text property -

First(ScannerControlName.Barcodes).Value

My ScannerControlName is SCANVIN

How can I populate barcode scanner value.

Try using the newer Barcode Reader control instead of the old Barcode Scanner control. In the barcode reader control, no need to put anything in the OnScan property.

Then in the text control, use:

First(ScannerControlName.Barcodes).Value

Where ScannerControlName is simply the name of your Barcode Reader control.

Are you using a barcode or QR Code? In the Barcode Reader control properties, be sure to select the type of code you are using.

Also, not sure if this matters, but I have typically used label controls instead of text input boxes to display the results.

Thank you for your response. However, it didn’t work as expected and didn’t display any value. Could you please suggest how we can make it work?

Any other details you can provide would be helpful. This should be a relatively simple fix.

@55552 I appreciate your help!

I have an app with 14 columns used to collect information with power app. Later, the production manager realized we need a QR code scanner, so I want to populate the Text Input field with the scanned QR code value. However, I'm not sure where the value from the QR code scan is being saved.

I removed the old Barcode Scanner (QR Code) and replaced it with a new one.

I've attached an image for reference.

@55552 Thanks you for your help!

It worked for me. However the value is not collecting to the Sharepoint list(as the app is supposed to collect data and save it in List.)

Can you please help me with the same.
