Introduction

Hardware

All AC-Hardware with a P5 Controller can use this feature once updated to 6.12.0 or higher.

...

USE-Case

For public charging stations, the AFIR requires a safe payment solution.
In the case of AC charging stations and wall boxes, this safe payment solution can be a QR Code in the display that links to a payment site.
The payment site, operated by the backend operator, can then handle the payment and send a RemoteStartTransaction to the charging point.
The AFIR additionally requires the QR codes to be charge point specific.

Implementation

The charging stations with FW 6.12.X and the following have the possibility for the operator to display a QR Code on the display.

...

In case of a communication error where the backend can not be reached a QR-Code will not be displayed to avoid problems with authentication. There will be an indication to the user that Ad-hoc payment is temporarily unavailable.
