A smart memory card (400, 900, 1000) communicates with a smartcard compatible device (500) and a memory card compatible device (600). The smart memory card includes a processor (402, 902, 1002) which performs smartcard functions and a memory (412, 912, 1004) for use with a memory card device connection which allows memory card compatible device operation. Cellular telephones (1300, 1600) facilitate the use of two types of cards therein.

A controller for a radiotelephone having the capability of operation in both a secure mode for call authorization and a nonsecure mode for user interface is disclosed. The nonsecure mode and secure mode of operation are both resident in a single microcontroller which runs the nonsecure operations until a requirement for the secure operation is requested during call placement. The nonsecure mode is disabled during the period of time the secure mode is operational and is reenabled upon completion of the secure mode operation. The secure mode cannot be accessed externally to the microcontroller.
