Provision of position data through a distance delimitation protocol

摘要

Procedure for the provision of the position data for a smart card (102) with sections for: - the reception (202) or determination of the position data of a location unit (130) by the location unit (130), wherein the location unit (130) is spatially separated from the smart card (102); - the transmission (204) of the location data of the location unit (130) to the smart card (102) through a contactless interface (118) using a cryptographic protocol (114); - the execution (206) of a distance delimitation protocol (112) between the smart card (102) and the location unit (130), wherein the distance delimitation protocol (112) concludes satisfactorily precisely then when the distance The space between the smart card (102) and the location unit (130) does not exceed a predetermined maximum distance; - the execution (210) of a smart card function (110) with satisfactory conclusion of the distance delimitation protocol (112), wherein the smart card function (110) uses the transmitted position data as position data indicating the current position of the smart card (102).
