The card is used for normal driving and permits savings, displaying,
or printing of activities under this identity.
Company card
(yellow)
The company card identifies a company, authorises access to the
company's data and can assign the DTCO 1381 to a company. This
card is intended for the owners and holders of vehicles. With this
card it is possible to display, print, and download the data assigned
to the company in the internal memory and on an inserted driver
card.
Control card

The control card identifies an official of a controlling body (like the
police) and permits access to the data in the internal memory. All
saved data and the data of an inserted driver card are accessible.
This data can be displayed, printed, or downloaded through the
download interface.

of the card will be mechanically blocked.

• the user requests withdrawal and
• after the data defined by the ordinance has been saved on the
tachograph card.
