RFID authorization
Certain device variants are equipped with an RFID reader, which enables the authorization of a charging
process with RFID cards in accordance with ISO 14443 and ISO 15693. The RFID authorization only allows
a charging session to be started if an identification takes place by means of an RFID card. The
authorization function is activated and deactivated in the web interface of the master charging station.
In the case of a local charging network without a higher-level OCPP backend, all RFID cards must be
taught in at the master charging station. Up to 1000 RFID cards can be stored. After teaching in, the
permitted RFID cards are stored on the master charging station and are managed by the latter
throughout the charging network. It is not possible to teach in RFID cards at a slave charging station.
When connecting to an external OCPP backend, all RFID cards must be taught in at the OCPP backend.
Any number of RFID cards can be stored. It is not possible to teach in the RFID card directly at a charging
station.
4.2.1.
Authorization modes
Once the authorization function is activated in the web interface, 3 authorization modes are available.
These determine which source is used first to retrieve the stored RFID cards. Depending on the
authorization mode, the charging station will behave differently if the connection to the OCPP backend
fails.

Behavior in the standard case
Behavior in case of connection

FirstLocal
The authorization request is first
checked against the RFID cards
stored locally on the charging
station. If the RFID card is not
stored locally and an OCPP
backend is used, it is checked
against the RFID cards stored on
the OCPP backend.
The authorization request is
checked against the RFID cards
stored locally on the charging
station.*)
FirstOnline
The authorization request is
always checked against the RFID
cards stored on the OCPP
backend. No check is made with
the RFID cards stored locally on
the charging station.
The authorization request is
checked against the RFID cards
stored locally on the charging
station.*)
OfflineNo Authorization
The authorization request is
always checked against the RFID
cards stored on the OCPP
backend. No check is made with
the RFID cards stored locally on
the charging station.
The RFID card is read and the
charging process is always
enabled. As soon as the
connection to the OCPP backend
is established again, the RFID
card is checked and the charging
process is aborted if an invalid
RFID card is used.
