Abstract
The subject innovation relates to a chip card to be inserted in terminals. An exemplary embodiment of the chip card includes a clock unit to provide a time reference and an internal power source to at least run the clock unit in case of absence of an external power source. The exemplary chip card also includes a signal receiver to receive a satellite navigation signal comprising a satellite time signal, the signal receiver being connected to the clock unit in order to synchronize the clock unit with the satellite time signal to enable the clock unit to provide the time reference as a trusted absolute time reference independently from a position of the chip card.
