Thank you for your question.
If the card is not present, it will fail and you will get notified. Since the vehicle periodically connects to WEB TACHO every hour once it has ignitions, assuming there are no other factors interfering and the vehicle has no issues sending its DDD files, then the only reason it can fail is due to the company card not being present or the vehicle's ignition being turned off in the middle of the task. So to enable the Failed Schedule Notification, you will need to go into the settings tab at the top of the page and enable the Failed Schedule Notification.
