Integrated Circuit (IC) Microprocessor Cards. Microprocessor cards (also generally referred to by the industry as "chip cards") offer greater memory storage and security of data than a traditional mag stripe card. Chip cards also can process data on the card. The current generation of chip cards has an eight-bit processor, 16KB read-only memory, and 512 bytes of random-access memory. This gives them the equivalent processing power of the original IBM-XT computer, albeit with slightly less memory capacity. Integrated Circuit (IC) Memory Cards. IC memory cards can hold up to 1-4 KB of data, but have no processor on the card with which to manipulate that data. Thus, they are dependent on the card reader (also known as the card-accepting device) for their processing and are suitable for uses where the card performs a fixed operation.
