The dynamic QR code

enables AFIR-compliant charging and ad-hoc payment at charging points with a charging capacity of less than 50 kW – simply, safely and, in the case of Technagon, without any retrofitting.

The dynamic
QR code

changes every 60 seconds and links to a URL for ad-hoc payment via a payment provider.

The URL

contains unique, static components for charge point identification, a time stamp and a one-time password.

The one-time password

is generated during the scan, added to the URL and can only be verified by the payment provider.

Ad-hoc payment

via the dynamic QR code is therefore a secure and reliable payment method.

URL structure and QR code examples:

Legend:

  • Landingpage
  • Versioning (increase by one number when adapting the link structure)
  • EVSE ID of the charging point
  • ID type: 0 = EVSE ID; 6 = serial number + connector ID
  • One-time token (TOTP)
