Hide scanned QR value in Form View

I want to hide the result from a scanned value of a QR code in a form view. I tried a format rule white text but it doesn’t work, something like password chars may work.


AppSheet does not provide a way to do “masking”, hiding the actual input characters as is often done for passwords. You could hide the entire column once it has a value using a Show? expression of ISBLANK([_THIS]).
