SD cards are compatible in many devices.
Secure Digital (SD) cards are a common type of memory that is interchangeable between different devices. Commonly used in digital cameras, cellular phones, MP3 players and other electronics, SD cards have a few variations, each compatible with different devices.
Standard SD Cards
Standard SD cards measure in at 24 mm long by 32 mm tall with a depth of only 2.1 mm. Devices capable of using SD cards typically say so in the documentation.
SDHC Cards
A Secured Digital High Capacity (SDHC) card has the same physical dimensions as a regular SD card. The only difference is that SDHC cards have more storage capacity. According to the SD Association, SDHC cards are backwards compatible with SD card devices after a firmware upgrade.
Micro & MiniSD
Micro and miniSD cards are smaller versions of the SD card. You won't have to worry about compatibility due to the physical size difference; you physically can't insert an SD card into a mini or microSD slot. MicroSD cards are compatible with SD and miniSD card devices through an adapter that allows these smaller cards to physically fit in the larger SD card slot.
