When you scan a business card from within the app, the CONTACT added shows "created by MOBILE_USER" and you have to go into the audit logs to see who was logged into the LC app when the business card was scanned.
I believe it would be really valuable to record in the contact the name of the user who was logged in when the business card was scanned and a new contact added.
I've recorded a video to show what I mean: https://www.loom.com/share/c3902bbcc95b47f1aac7cdae5ca9a6b4
