USB FlashCard is a flash memory card format developed by Lexar, and announced on December 13, 2004. There is a plethora of existing memory card formats such as SD, xD, and CompactFlash; the major advantage of USB FlashCard is that the cards are in fact standard USB flash drives. The USB FlashCard uses a modified USB Type A plug which keeps the total thickness of the card to under 4.5 mm. Because of its small size and USB compatibility, a USB FlashCard could, for example, be accessed by either a digital camera or a modern personal computer without the need for a card reader. Lexar has published the specifications for its USB FlashCard form factor on its website in an open and royalty-free format, in the hopes that other memory card and portable device manufacturers will adopt it.
