{{lowercase title}} [[File:TwinMOS 2GB microSD 20100117.jpg|thumb|2 GB microSD]] [[File:SD Cards.svg|thumb|SD card, miniSD card, and microSD card]] [[File:MicroSD & Adapter.jpg|thumb|upright|MicroSD card with adapter for use in a slot for full SD card]] '''microSD''' is a type of removable [[flash memory]] card used for storing information. SD is an [[abbreviation]] of [[Secure Digital card|Secure Digital]], and microSD cards are sometimes referred to as µSD, uSD, or mSD.<ref>{{Cite web|url = https://learn.sparkfun.com/tutorials/sd-cards-and-writing-images|title = SD Cards and Writing Images}}</ref> The cards are used in [[mobile phone]]s, [[Camera|cameras]], [[Handheld game console|handheld game systems]], and other [[mobile device]]s. It is the smallest [[memory card]] that can be bought; at 15&nbsp;mm × 11&nbsp;mm × 1&nbsp;mm (about the size of a [[fingernail]]), it is about a quarter of the size of a normal-sized [[SD card]].<ref>{{cite web |url=http://www.sdcard.org/developers/tech/microsd/ |title=microSD Card |publisher=SD Card Association |access-date=2008-09-13 |archive-date=2010-01-23 |archive-url=https://web.archive.org/web/20100123221944/http://www.sdcard.org/developers/tech/microsd |url-status=dead }}</ref> There are [[adapter (computing)|adapters]] that make the small microSD able to fit in devices that have slots for standard SD, [[miniSD]], [[Memory Stick]] Duo card, and even [[USB]]<!-- OCZ Trifecta -->. But, not all of the different cards can work together. Many microSD cards are sold with a standard SD adapter, so that people can use them in devices that take standard SD but not microSD cards. TransFlash and microSD cards are the same (they can be used in place of each other), but microSD has support for [[Secure Digital card|SDIO]] mode. This lets microSD slots support non-memory jobs like [[Bluetooth]], [[GPS]], and [[Near Field Communication]] by attaching a device in place of a memory card.<ref>{{cite web|url=https://www.phonescoop.com/glossary/term.php?gid=179|title=microSD definition (Ph
