How to send a signed paper contract from your Android phone when working in the field

I was out meeting clients today and urgently needed to send a signed contract to a vendor who only accepts fax. Since I didn't have access to an office scanner, I searched for a quick mobile workaround. I found https://best-free-fax-app-for-android.com/, which compares top Android fax apps. I installed Municorn Fax App, snapped a photo of the pages using its built-in scanner, and sent the document in under two minutes straight from my screen.
