Abstract: A dual mode smart card controller, a dual mode smart card, and a wireless communication device incorporating one or more of the same are provided. The dual mode smart card controller includes a first controller adapted for supporting communications with a first smart card protocol, and a second controller adapted for supporting communications with a second smart card protocol. The dual mode smart card controller further includes a multiplexer module having two sets of multiplexed ports that are selectively coupled to a common set of ports, and an interface module coupled to the common set of ports, and adapted to be coupled to signal terminals of a smart card. The multiplexer module selectively couples one or more signals received from the smart card via the signal terminals to one of the first controller and the second controller. The smart card uses at least one of a same connection associated with the common set of ports for use with both of the first controller and the second controller.
