The standard was developed by Taiwan's Industrial Technology Research Institute and is capable of scaling up to an astonishing 2,048GB of data.
The removable storage cards measure 12mm x 21mm x 1.95mm and can be plugged directly into a USB port. They will also fit into standard SD card slots with an adaptor.
"MMCA developed the miCard specification to provide manufacturers a solution that is adaptable and convenient for consumers," said MMCA chairman Yves Leonard.
"Adding USB 2.0 capability to a memory card provides an interface that is compatible with existing products and widely recognised by general consumers."
The card will be capable of data transfer rates of 480Mbps, the same speed as USB2.
Twelve Taiwanese companies have so far signed up to produce the card by the end of the year. Full engineering specifications will be announced this month.
