Once your company has a D Card contract, you can choose between a physical D card for fuel and AdBlue® solution payments and AVR – or use both is most suitable for your company! Automatic vehicle recognition (AVR) is based on modern and safe technology. Fuel can only be refuelled in a vehicle with a special AVR sensor. The Teboil KorttiExtranet online service shows AVR purchases nearly in real time but you can also print a receipt at the station after refuelling.
