The microSD card is based on TransFlash, which was developed by SanDisk in cooperation with Motorola and is the world's smallest flash memory card form factor. SanDisk's TransFlash cards were recently adopted by the SD Card Association (SDA) and renamed "microSD."

The new microSD card is fully compatible with TransFlash card slots and is designed as a small, flash memory storage card for mobile phones and devices. The company will continue to support existing TransFlash product lines and will transition its handset customers and the retail channel to the renamed microSD card over the next several months.

• Universal compatibility with TransFlash memory card slots
• Comes bundled with an SD Adapter for use with microSD or TransFlash cards.
• Built-in security features enable users to download, store, and play secure content just like an SD card.
