Barcode widget in Enketo webform

1. What is the general goal of the feature?
To be able to scan qr code using Enketo webform

2. What are some example use cases for this feature?
We use barcode in ODK collect for data collector identification so it does not misspell the names. But we have a form that requires collection of data in table format so we use the grid-theme of Enketo for that particular form. However, the barcode widget does not work. We use the Enketo form offline. So asking them to login to central for identification is not possible.

3. What can you contribute to making this feature a reality?
We can source funds for the development.
