Digital Tachograph System
Polish Digital Tachograph System (STC) is a system that uses new technologies to ensure security and integrity of data describing drivers’ working time. The system is less susceptible to records tampering than the old analog system. It allows easier and more effective control of drivers' working hours by their employers and by control authorities.

The basic assumptions of the digital tachograph system are based on the following principles:
  • road safety improvement,
  • compliance with social legislation relating to drivers' working time,
  • augmentation of competition between transport companies.
The latest generation of digital tachograph system opens up new opportunities in fleet management to transportation carriers.

Digital Tachograph System (STC) - the entity issuing digital tachograph cards in Poland is PWPW S.A. The company is responsible for delivery of:
  • Driver cards – used to record drivers’ working hours and distance travelled.
  • Workshop cards – issued to authorized technicians servicing digital tachographs. The workshop card is personalised to an individual technician and protected by PIN code.
  • Company cards – for companies providing transit services; the cards are used to lock and unlock tachographs in order to gain access to company data.
  • Control cards – issued to a national transport control authority; allow to download data and monitor drivers’ working hours.
