In order to use the vehicle unlock feature, each person that should be allowed to use the vehicle needs to have a card.
Each card has an identifier belonging to the card. This identifier must be stored with the user of the person.
When the person is trying to unlock the vehicle with their card, then vehicle is checking in our application if the person is allowed to use it. This is done over the cards identifier (short card id).
Add a card id to a user
The card ID can be found on the cards themselves. Don't copy the leading zeros.

Every admin user can add the cards id to a user.
This can be done with the following steps:
Read out the cards id with a RFID reader
Navigate to the user that you want to add the id to
Add the card id into the card id field
Save the user
