'''microSD''' is a small, removable [[flash memory]] card format originally based on SanDisk's TransFlash card format. It is primarily used in mobile phones, but because of its size and increasing capacity it is also being used in handheld [[GPS]] devices, portable audio players, flashcards for [[Nintendo DS]], and expandable [[USB flash memory drives]].

{{Redirect category shell|

At 15 mm × 11 mm × 0.7 mm—about the size of a [[nail (anatomy)|fingernail]]—it is currently the smallest [[memory card]] format commercially available. It is about one quarter of the size of a standard [[SD card]] but can be inserted into an [[adapter (computing)|adapter]] which allows the card to be used in devices with an SD card slot.

TransFlash and microSD cards are essentially the same, and each can be used in devices made for the other type. There is one exception, which is that unlike TransFlash, microSD devices have the capability to support [[Near Field Communication|NFC]] (Near Field Communication).

[[As of 2006|As of January 2007]], microSD cards are available in capacities from 64 MB through 2 GB but KingMax and SanDisk have announced 4GB cards (34 GB/cm<sup>3<sup>).

== History ==

[[Image:MicroSD vs SD.jpg|thumb|250px|right|A microSD card next to its SD adapter]]

The microSD format was originally created by [[SanDisk]]. It was originally called '''T-Flash''', and then '''TransFlash''', before being rechristened '''microSD''' when adopted by the [[SD Card Association]] (SDA). Other flash card formats approved by the SDA include [[miniSD]] and [[Secure Digital Card|SD]].

The SDA announced the microSD format at CTIA Wireless 2005 on [[March 14]], [[2005]], and approval of the final microSD specification was announced on [[July 13]], [[2005]]. At launch, the microSD format was available in capacities of 32, 64, and 128 MB. SanDisk introduced a 2 GB microSD card in July of 2006, initially priced at US$99.

== Manufacturer support ==

The format is currently supported primarily by mobile phone manufacturers, of which [[Motorola]] was the first adopter. [[Garmin]] produces a line of [[GPS]] receivers that ships with microSD cards for map storage.

Furthermore Navman GPS devices also use microSD cards for extra map storage of different countries.

All devices which support SD cards can support microSD cards using an SD card adapter (often included in the package of a microSD card), increasing the full compatibility list. SanDisk has a list of mobile phones with memory card support [http://www.sandisk.com/Assets/File/Compatibility/Mobile_Phones_with_Memory_Cards.pdf]

(in [[PDF]] format) which gives the type of the memory card slot, and also lists the still-image camera support, video capture support and music support.

SanDisk's E200 series MP3 players also support microSD card expansion, allowing additional capacity of up to 2GB presently. It is not known if larger capacities are supported.
