Managing and using RFID

The Wallbox supports various authentication methods via OCPP.
In addition, it is possible to save the user IDs of authorized RFID cards in a local,
preconfigured list.
You manage the RFID cards via the following channels:
• Modbus controller
• OCPP-based server
• On the device using Admin RFID cards
The management of RFID cards via Admin cards in the local, preconfigured list is described
under Releasing or locking RFID cards.
