I've been using it now for several weeks and it's very secure. Never get tired of those little points reminders on my phone when I'm shopping!
After using only once I understood how it all worked...great to see the businesses personality in the reward schemes.
Linking up my bank card to the app only took a minute and I love how it rewards me when I pay as normal.
Simply one of the greatest ideas when it comes to making loyalty appealing to everyone!
