Validating Data in a Scanned QR Code

I would like the user of the form to be able to scan QR codes to repond to questions.

I will provide the QR codes that will be scanned.

I want to make sure that only the QR codes I provide can be scanned.

Is there a simple way to do this? Can it be done with a mask? IE all my QR codes start with a unique set of numbers and it gives an error if the QR code that is scanned does not begin with that set of numbers?

Thanks!

To my understanding, you would like to use your form to scan QR codes and if the codes scanned does not start with a specific set of number you would like to show an error or prevent submission.

If that is the case, you can use our QR Code Reader widget.

The QR Code Reader widget works with conditions.

You can use the value the QR Code Reader widget scans to trigger conditions that you can set up on the form.

You can use the Paragraph element on the form to create an error message that will be shown based on the scanned code.

Please give it a try and let us know if you need any further assistance.
