3.3 millimeters, which is conceived mainly for use as external memory. Version 2 of
the PCMCIA specification also defines a card Type II with thickness of 5 mm and a
card of the Type III with a thickness of 10.5 mm. Type II cards can realize devices
such as modems, fax and network interface cards. Type III cards are equipped
with devices that require more space, for example wireless communication
modules or rotary storage media (hard disk drives, for example).
