information sign

This page describes a key prefix rather than a simple key.

Some charging stations require authentication ("unlocking"), even if charging is for free. Different operators use different authentication mechanisms for their charging stations. Some charging stations even support several authentication mechanisms, and the user can choose which to use.

Authentication vs Payment

This key is only concerned with the authentication method, not the payment method. If you can pay directly without having to register or be part of a network, then use authentication:none=yes.

To denote whether a charging station is free or not, use fee=yes/no. For payment methods, use the payment:*=* key. To denote whether a charging station is public, or only accessible to a certain group, use access=*.

  • authentication:chip_card=yes/no - authentication by inserting a membership card with a chip into a chip card reader
  • authentication:key=yes/no - authentication by using a physical key
  • authentication:none=yes/no - the station can be used without authentication (note: this does not mean that charging is free!)
