I'm wanting to build an inventory app, similar to your sample.
I would like to be able to implement a qr or barcode scanner with a connected camera or phone to get serial numbers of an item?
That's a great idea! At the moment we do not have any native support for cameras, but as you may have heard we recently announced the Tadabase API. We're very excited about this feature since it allows your apps to connect with external applications - including camera applications (if they have an API). If you're interested in requesting API access please visit https://tadabase.io/developer-api and fill out the corresponding form.
