It’s all made possible by using the Opening Banking APi’s. We have access via apis to over 20oo Banks in the UK and EU.
You choose and connect to your bank via the WWUB, give permission for WWUB to view your transaction, with your permission we can see when you make a purchase with one of our merchants and once this matches a current offer then we create a game, it’s safe and the process of banking api’s is governed by the financial authorities.
You don’t have to change anything you normally do, you just connect your bank account or card to WWUB pay for the things you like to buy from the merchant you like, and pay in the way you like, and get a free chance to win you money back.
