Abstract
The invention concerns a method (300) and system (100) for identifying and receiving data from an accessory (110). In one arrangement, the method can include the steps of generating (312) at least one signal having at least one predefined frequency in which the predefined frequency corresponds to an identity of the accessory, receiving (314) the generated signals at a portable electronic device (112) and at the portable electronic device, identifying (320) the accessory based on the predefined frequency of the received signal. In another arrangement, the predefined frequencies correspond to a function performed by the accessory, and the method can further include executing (322) a corresponding function in the portable electronic device based on the predefined frequency that corresponds to the function performed by the accessory.
