[Updated from 16th August 2018]
Update: Unfortunately Instagram have removed the Nametag scanning feature from Stories. I think this is a step backwards as it was much quicker to scan Nametags through the Stories camera rather than visiting the Explore page. Instagram have also decided to change the name from “Name Tags” to “Nametags”… not sure the reason for that one.
Another new Instagram feature has just been rolled out… Instagram Nametags!
