Abstract

An access system for an object with a transmission unit arranged in the object and a transponder unit arranged in a portable device. The transmission unit emits request signals at regular intervals. The transponder unit, in response to a triggering event, stores a current position of the object and determines its own position at regular intervals. The transponder unit deactivates the transmission unit when the transponder unit detects, based on the determined position, that the transponder unit has left a first zone, wherein the first zone is arranged around the object, and wherein the transmission unit does not emit any request signals while the transmission unit is deactivated. The transponder unit furthermore activates the transmission unit when the transponder unit detects, based on the determined position, that the transponder unit has entered an adjusted first zone, wherein the adjusted first zone is arranged around the object.
