Power Apps – navigate to another page after barcode scan

How to let user go to another page only when he scans the right barcode?

Let´s write this to the OnChange property of scanner:

• If(
     Concat(
        BarcodeReader1.Barcodes,
        Value,
        ","
        ) = "123456",
     Navigate(
        Screen2,
        ScreenTransition.Cover
     )
  )

How does it work?

The scanner produces values as the array of records. You can merge it into one using Concat. And than compare it with proper value.
