Abstract
In one embodiment, a near field communication (NFC) device is provided, comprising: a communication unit configured to be communicatively coupled to an NFC reader; a processing unit configured to use a plurality of emulated cards for executing one or more applications; a profile determination unit configured to determine a polling profile of said NFC reader, wherein the polling profile represents a sequence of predefined radio frequency (RF) transmission events, and wherein the profile determination unit is configured to determine said polling profile by comparing a detected sequence of RF transmission events with one or more predetermined sequences; a card selection unit configured to select a specific one of said emulated cards for use by the processing unit in dependence on the polling profile determined by the profile determination unit. In another embodiment, a corresponding method of operating an NFC device is conceived. In another embodiment, a computer program is provided for carrying out a method of the kind set forth.
