CARDS - What is a SDXC card ? SDXC is the latest type of memory card released in 2010 which meets the demands of FULL HD recording in terms of capacity and speed. The SDXC card has the same dimensions of a SD and SDHC card, but is ONLY compatible with SDXC devices.
1 Asymmetrical slots in the sides of the SD card prevent inserting it upside down (while an MMC goes in most of the way but makes no contact if inverted).  Most SD cards are 2.1 mm (0.083 inches) thick, compared to 1.4 mm (0.055 inches) for MMCs. The SD specification defines a card called Thin SD with a thickness of 1.4 mm, but they occur only rarely, as the SDA went on to define even smaller form factors.
