A-Data SD cards with capacity display

We're always wondering how much junk we have on our various SD cards; thanks to A-Data, we can tell at a glance. Similar to the JumpDrive with E Ink, A-Data added a tiny liquid crystal display on their BCD-SD cards. The LC display uses power from a host while inserted and indicates the remaining capacity on the card. Pop the card out and the display retains the information until you reinsert it, so you can manage your data needs. A-Data BCD-SD cards come in the typical SD flavors: 128, 256, 512MB as well as 1 and 2GB.
