Sushi and bento restaurant chain Wasabi is overhauling its loyalty programme, making it easier for customers to earn rewards by automatically adding stamps to their accounts when they buy food - without having to scan a QR code or present a loyalty card. Wasabi has teamed up with Bink , a loyalty app, to ensure that customers are able to earn rewards whenever they make a qualifying purchase with a linked payment product. Bink's 'Payment Linked Loyalty' platform is linked with Acteol's Single Customer View to identify and reward customers every time they shop. The technology links into a partner's - in this case, Wasabi's - website and channels to provide the experience.
