Creating Barcode Database in SharePoint Online

[MilanVuletic]

Hello, 

Is it possible to create database where once a barcode is scanned the data will be sent to a sharepoint page or site? 

Also is it possible for SharePoint to autogenerate a barcode once specific fields have been added

This is not really a SharePoint thing, but of course this is something you could integrate in SharePoint by doing some custom coding or with Power Automate. What you need here is the QR generation part that can be done by third party services
