A smart card, also known as an Integrated Circuit Card (ICC), is a micro-controller based access module. It is a physical/logical entity and can be either a Subscriber Identity Module (SIM) or a Universal Integrated Circuit Card (UICC). Originally, the ICC defined for 2G networks was the SIM.
The previous column included a partial listing of the data or information that may reside on a SIM card, all of which could have potential probative value in an investigation. This data or digital evidence is scattered throughout the Elementary Files (EF). Although a thorough discussion of all the potential evidence that could be on a SIM card is beyond the scope of this column, some of that information will be discussed in this and a future column.
