Memory card reader

A memory card reader is a device for accessing the data on a memory card such as a CompactFlash (CF), Secure Digital (SD) or MultiMediaCard (MMC).

Some printers and Smartphones have a built-in card reader, as do many laptops and the majority of Tablet computers.

Multi card readers do not have built-in memory capacity, but are able to accept multiple types and styles of memory cards.

Memory card readers, unlike smartphones, telephones and other devices, such as cameras and digital cameras, allow formatting in a file system other than FAT (FAT16, FAT32, exFAT) to NTFS in Windows, ext, ext2, ext3 in Linux or HFS, HFS + for Mac OS.
