With more than 4.4 billion visitors per year across over 15,000 REWE Group stores and travel agencies in 21 countries, we know exactly what consumers and merchants need when it comes to payments. We strongly believe in making payments seamless and invisible, while linking them with value-added services as part of a reliable identity service. Our mantra: #wesolvepayn. We combine cutting-edge technology with rigorous security standards to protect sensitive payment data while fostering innovation in a cloud-native technology environment.

You love it when a plan comes together?
