1. A smart memory card, comprising:
- a body;
a smart card device including a processor positioned in the body and a first memory positioned in the body, the first memory storing a subscriber identity used by a cellular telephone to provide subscriber information to access a cellular system; and
a memory card device positioned in the body, the memory card device coupled to the smart card device, the processor accesses the memory card device to make a pay call through a cellular telephone using the subscriber identity and debits the memory card device when the smart memory card is connected to a cellular telephone and the memory card device is debited to make a call without the subscriber identity when the smart memory card is connected to a memory card compatible device.

Abstract
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.
