A-Data won the Best of Innovations Award for CES 2007 on the Super Info SD Card. The A-Data Super Info Secure Digital card uses bi-stable EPD (Electrophoretic Display) technology to display available space on left of the flash memory without needing any additional power.
In addition, one can use 2, 3 or 4 characters to ID the SD card. As seen in this photo there is a full 2GB Secure Digital flash card used for the photo-shoot.
Kicking around in technology since 2002. I like to write about technology products and ideas, but at the consumer level understanding. Some tech, but not too techie.
Posting on Quora.com as well.
