I am renting an electric car for a longer trip and figuring out how to pay for (fast) charging stations in Germany and The Netherlands. As of 2022, most charging stations do not yet allow paying for with a regular bank card (this will change from 2023), and dedicated cards or smartphone apps are still needed. The charging card uses a Radio-frequency identification (RFID) chip (contactless), but how is this for the smartphone apps? Can I scan a Quick Response (QR) code or does it need to support Near Field Communication (NFC)?
My smartphone does not support NFC, and I'm trying to understand if I need to order cards from the (largest) roaming providers (those cards cost money), or if I can count on my smartphone for paying at (fast) charging stations.
