Offline charging and unknown cards

At every scan your station asks DenkCharge whether the card may charge on that station. Some stations can also make that decision themselves, with settings in the station. You configure those on the station itself, not in DenkCharge; check your station’s manual or ask your installer.

When the station has no connection

• LocalAuthorizeOffline (on OCPP 2.0.1: AuthCtrlr.LocalAuthorizeOffline): without a connection, the station lets cards charge that are in its local card list or cache.
• AllowOfflineTxForUnknownId (on OCPP 2.0.1: AuthCtrlr.OfflineTxForUnknownIdEnabled): without a connection, the station lets any card charge, including a card it does not know.

When the station does have a connection

• LocalPreAuthorize (on OCPP 2.0.1: AuthCtrlr.LocalPreAuthorize): the station starts right away for cards in its local list or cache, without waiting for the answer from DenkCharge.

A session with a card that is not in your account shows in the app as "Unknown card". A blocked or lost card from your account is simply shown with its name.
