means the capacity of systems and the underlying business processes to exchange data and to share information;
- motion sensor
means a part of the tachograph providing a signal representative of vehicle speed and/or distance travelled;
- non-valid card
means a card detected as faulty, or whose initial authentication failed, or whose start of validity date is not yet reached, or whose expiry date has passed;
- normal residence
means the place where a person usually lives, that is for at least 185 days in each calendar year, because of personal and occupational ties, or, in the case of a person with no occupational ties, because of personal ties which show close links between that person and the place where he is living.
- open standard
means a standard set out in a standard specification document available freely or at a nominal charge which it is permissible to copy, distribute or use for no fee or for a nominal fee.
- periodic inspection
means a set of operations performed to check that the tachograph works properly, that its settings correspond to the vehicle parameters, and that no manipulation devices are attached to the tachograph;
- record sheet
means a sheet designed to accept and retain recorded data, to be placed in an analogue tachograph, and on which the marking devices of the analogue tachograph continuously inscribe the information to be recorded;
