Mercedes-Benz is revolutionising the way their customers fuel up in Germany by introducing a seamless and secure payment system directly from their cars using their fingerprints. This innovation is facilitated through the native in-car payment service, Mercedes pay+. The biometric two-factor authentication is made possible by a fingerprint sensor integrated into the MBUX infotainment system.

When a driver arrives at a connected service station and turns off the engine, the Mercedes me Fuel & Pay service automatically initiates on the MBUX infotainment system. The driver can then select the desired gas pump. Even before refueling, the system calculates the maximum total amount based on the current fuel price and the estimated fuel required to fill the tank.

In this advanced system, drivers no longer need to authorize payments via their mobile devices. Instead, they complete transactions seamlessly through fingerprint authentication. After refueling, the MBUX display shows the amount of fuel added and the invoice amount. Payment is processed automatically, allowing the driver to leave the gas station without visiting the checkout area. The invoice is later sent to the customer via email.
