Currently there are two possibilities to start and stop your charging session at public charging points. Either you authorise the session with the RFID card (by holding it to the card reader of the charging point). When you start a charging session with the RFID card, you must end it also with the RFID card.
Another way to start the charging session is to start it via the app. Select the charging point, connect the cable and click on “start charging” – after a couple of seconds (depending on your internet connection and the servers of the Charging Point Operator) the session will start.
