If your driver gets a new tachograph card, it's important to update their Tachograph Card ID in the Mapon platform to avoid issues like duplicate profiles and inaccurate tracking. Updating the card information before the driver starts using the new card ensures proper tracking, especially in solutions like Driving behavior.

You can do this by going to the Drivers section, editing the driver's profile, and entering the new tachograph card number in the 'Tachograph Card ID' field.
