ExpressCard is simpler and cheaper to implement than PC Card Because ExpressCard harnesses buses that already exist on a host system, it doesn't require a separate ASIC to integrate it to a host system. This is referred to as the extended portion of the card and ExpressCards with such a configuration are referred to as extended cards.
The extended portion can exceed the card dimension in any axis, but there are obvious practical limitations to how much. Either form factor is allowed additional volume extending outside of what would be considered the flush portion of an inserted card.
