The SD (Secure Digital) Memory Card is a highly-sophisticated memory device about the size of a postage stamp. SD Memory Cards stand to revolutionize information, entertainment and communications by putting advanced digital storage technology quite literally at your fingertips.

SD Memory Cards are non-volatile, which means they do not require power to retain the information stored on them. They are solid-state devices, so they have no moving parts to skip or break down. They will offer an incredible combination of high storage capacity, fast data transfer, great flexibility and excellent security. And of course, incredibly small size.

SD will facilitate fast, simple, secure downloading of all types of digital files, like music, movies, photos, news even cooking instructions for your microwave. Once downloaded to your PC, you can organize and store the files as you wish. Then easily transfer the files from your PC to a super-compact SD Memory Card, which will be accepted by a whole variety of future SD-enabled products. Of course, you will also be able to directly record your own audio, video, still photos, and more onto SD Memory Cards, as such products become available.
