USB FlashCard

USB FlashCard is a flash memory card format developed by Lexar, and announced on December 13, 2004.[1]

There is a wide range 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.[2] 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[2] on its website in an open and royalty-free format, in the hopes that other memory card and portable device manufacturers will adopt it.

Physical size

The specifications for the USB FlashCard published by Lexar show its dimensions to be 31.75 mm × 12 mm × 4.5 mm. The volume is comparable to the widely-adopted SD cards (32 mm × 24 mm × 2.1 mm). The USB FlashCard has nearly the same length as the SD card, but is half as wide, and approximately twice as thick.
