A memory card reader is a device that can read flash memory cards and transfer their contents to a computer. Flash memory cards come in many types and formats and provide removable storage for digital devices such as camcorders, cameras, MP3 players, and cell phones. There are single and multi card readers and while the former can only read a single type of memory card, the latter can read a variety of formats.

Without a memory card reader, a person has to directly connect the physical device that uses the memory cards to the computer. This is usually done with a Universal Serial Bus (USB) or Firewire cable. The advantage of a reader is that memory cards can be read directly on the computer, without connecting the device. This greatly simplifies the use, storage and organization of the cards. It also saves batteries and wear and tear on your camcorder or other digital device.

It is common for people to have more than one device that uses flash memory cards, and each device uses a different type of card. A multi-card reader accepts a variety of formats, making it useful for all your memory card needs. These readers usually have two or more slots to accept cards of different sizes.
Memory card readers are usually connected through a USB port.
Some memory card readers are extremely compact, barely larger than the cards they read. They plug directly into the USB port and are about the size of a memory card. Others are designed to be installed internally in a free bay on desktop computers, with a variety of options between these two models. An advantage of the external model is that it is portable, so it can be used with multiple computers and/or laptops at home.
Cell phones may contain memory card readers.
Many newer computers, including many laptops and notebooks, have a built-in card reader by default. Printers and even some monitors can also have them, so the information on the cards can be easily printed or displayed. Anyone considering replacing an old desktop, laptop, printer, or monitor may want to consider these options first.
When purchasing a reader, consumers should ensure that it is compatible with the required card types. This includes the capacity of the card as well as the format. Some models may not read flash memory cards larger than 1 GB, for example. Buyers should also note that a more flexible card reader that supports additional formats can make the device a bit more future-proof, should they buy more digital devices later or replace the ones they already have.
Memory card readers are usually extremely affordable and can be found at many online retailers and local computer and digital equipment vendors.
Digital photos are often stored on memory cards.
