Is there a jotform widget that can read barcodes?

We have a QR Code Reader that can be placed on jotforms to Read QR Codes but unfortunately it doesn't appear to read "barcodes" which I think is what you might be looking for.

Would you mind explaining to us an example of the workflow for this that you seek?

Perhaps we could come up with a workaround for you or even make a request for this on your behalf if needed.
