Abstract
A portable device includes an active device (communication station) configuration for contactless communication with at least one external data carrier and a passive device (data carrier) configuration for contactless communication with at least one external communication station. A detection circuit is provided to detect the presence of an external data carrier and/or the presence of an external communication station in a communication zone of the internal active device configuration and/or the internal passive device configuration. An activation circuit is coupled to the detection circuit to enable one of the two configurations based on the detection result.
