As an EMP, you should have a QR code scanner implemented in your app so that the end users can scan the QR code and will be redirected to the page of that EVSE ID.
Here is an example of a QR code displayed on EVSEs:
As an EMP, you should only redirect to EVSEs that are available in your app. If the EVSE is not available, then the QR code should display an error message. For instance, ‘EVSE ID not available in this app’.
In the URL, the value EVSEID is given (evseid=xxxxx). Your app should expect to receive this URL in order to recognize the charging point, e.g.:
URL: https://m.intercharge.eu/evse/show?evseid=DE*HUB*030*000012
