  - About SD Association
    
    Founded in January 2000 by Panasonic, SanDisk and Toshiba, the SD Association is a group dedicated to establishing SD standards and facilitating their adoption and development.
    At its outset the Association represented just 14 member companies and has grown into a global alliance comprised of around 1,000 member companies. By developing and adopting SD standards, members enjoy better compatibility of member cards between devices, greatly enhancing consumer enjoyment and convenience.
