Charge and pay without downloading anything: the QR that replaces a card

For a driver who charges just once at a new location, asking them to register, download an app or request an RFID card is the fastest way to lose them. QR payment is designed exactly for that situation.

How it works, step by step

  1. The driver scans the charger's QR code with their phone camera — no app needed, it opens directly in the browser.
  2. They see the price per kWh and the charger status before committing to anything.
  3. They enter their card details for a pre-authorisation (a security hold, not the final charge).
  4. The charger starts remotely as soon as the pre-authorisation is confirmed.
  5. When they unplug, they're billed for exactly what they consumed — not a cent more — and the rest of the pre-authorisation hold is released.

The entire process happens in the phone's browser, in a single session, with no account creation and no password to remember.

Why pre-authorisation instead of a fixed charge

Charging a fixed amount upfront would mean either overestimating (to avoid falling short if the session runs long) or issuing a refund afterwards if it was shorter. Pre-authorisation solves this: a security margin is held on the card, but only the actual amount consumed is captured when the session ends.

A receipt, if you want one

When charging is complete, the driver can request a receipt (energy consumed, amount charged, duration) by email — handy if you need to expense the charge, for example on a business trip.

What if I want something more permanent later?

QR payment doesn't commit you to anything. If the driver starts charging regularly at a particular brand, that brand can offer them a dedicated portal with a saved card, prepaid balance or a monthly subscription — but that's their choice to make, not a requirement for charging the first time.
