How do I Leave after an in-store purchase?

Once you've finished your purchase, and are physically walking out of the store, it's a good idea to tap the 'Leave' button - basically, this 'checks you out' of the store. Don't worry too much if you forget, you can do it at any time, and after a period of inactivity your app will also automatically do it. 

1. Tap the Leave button at the buttom of the screen (see screenshot attached)
2. Points are automatically added to your profile & a receipt is sent to your email
