SD Card
Compact and Powerful, Ideal for Small Products
The SD card measures a mere 24mm x 32mm x 2.1mm approximately the size of a postage stamp. The slim, compact design promotes easy handling, an important factor for a "bridge media" that can be moved between different products. Using decoder software, an SD compatible device can play music, video clips and more without a drive mechanism like those in CD and DVD players. This allows the equipment to be more compact and gives product designers new creative freedom. Reliability is also improved through the elimination of skipping on music and video files.
