Step 1. Find the 'Wallet' icon
To be honest, this was the step we had the most difficulty with. As Android V6.2 users, the Wallet option didn't automatically show up. If you're having the same problem, find out how to add the Wallet here.
Anyway, we digress. The Wallet is normally located under 'Me', the far-right button on main menu bar at the bottom of the screen.
