ABSTRACT:
A cellular telephone (10) incorporates the electronics for implementing both a cellular telephone function (46) and a smartcard function (45). This allows the electronics to be protected from damage by the housing associated with the cellular telephone and also decreases the likelihood that the smartcard will be lost or stolen. The cellular telephone 10 also includes an RF interface (40) for wireless communication between the smartcard and an external reader. Further, by making use of the cellular telephone function, information associated with the smartcard function may be updated or modified via existing cellular telephone infrastructure.
