First of all, make sure that you have allocated sufficient credit to the fuel & charge card in the NAVIT app.
Open the partner app (e.g. Ryd, Pace, Shell or another fuel or charging app).
Add the card data of the NAVIT Fuel & Charge Card (click on card details in the NAVIT App) as a payment method in the partner app.
Find a petrol station or charging station in the partner app and drive to the station.
Select the petrol pump or charging station in the partner app.
Refuel or recharge and confirm payment.
With the fuel card, you no longer have to check out at the petrol station counter, but can pay conveniently via app.
Continue driving.
