Microsoft Forms, Flow, and SharePoint for contact sharing | Tracy van der Schyff
I like the approach to using this combination of tools (Flow, Forms, SharePoint) to solve a specific need (contact distribution). Where I struggle a bit is the "last mile" of people not necessarily having access to a QR code reader to start the process.
When designing solutions using Office 365 tools make sure you are keeping the entire user experience in consideration. If you don't have each step addressed and have unintentionally introduced a barrier to adoption in your process you have almost doomed your solution before you start.
