RFID/LED boards

One common authentication method is RFID (radio-frequency identification) chips. This also includes NFC (Near Field Communication) technology. These form the basis of all charging cards. Central to the identification is the so-called UID (Unique IDentifier) of an RFID chip. This is a unique code that represents the identity of a chip.

1. Hardware

Here's a list of available HMI RFID hardware modules:

1.1. Associated equipment

1.2. Installation and activation

The RFID module is placed beneath a semi-transparent part of the charging system housing. It should be positioned with a minimum distance of 20 mm from any metal surfaces or metal components to ensure optimal reading performance.

  1. Log in to the Legacy Config UI using the Manufacturer Login Credentials
  2. Under Manufacturer set Enable RFID to On
  3. Under Manufacturer, set Type of Display to Bender LCD-Module DPM2x16FP
  4. At the bottom of the Legacy Config UI, click to apply the changes
tip

When no RFID module is installed, set Enable RFID to Off. This prevents error messages.

info

When presenting a RFID that either has not been presented for a while or has never been presented, it might take some time for the backend to recognize the RFID. When the LEDs show that the card has been rejected, wait some time and present it again.

The status LED is to be found on the front of the controller.
