Memory Card Reader

Memory cards are used in a large number of electronic gadgets including digital cameras, mobile phones, and laptops. They are a great alternative to optical discs and thumb drives for storing all kinds of digital media. However, it can be a problem transferring the contents of a card to a computer or another gadget if the card is not supported. The memory card reader solves this problem by providing support for one or more cards. There are single card readers, serial readers that hold several cards of the same type, and multiple card readers that support a large number of different types.

Memory cards are small, removable storage devices that use a flash memory chip to store media. They have a plastic enclosure with a label on one side and a row of contacts on the other side. The media can be any kind of digital data including music, photos, videos, and documents. Over the years, there have been many different brands of memory card launched including CompactFlash, Secure Digital, and Memory Stick. Almost all of the brands are incompatible with each other which makes it difficult for device manufacturers to support them all. There are even smaller versions of some brands which are incompatible with the larger cards.

A single memory card reader is little more than a plug and a card slot. They typically support only one or two cards and have a fixed USB or Firewire plug. They are about the same size as a thumb drive and can be attached to a keyring or worn around the neck with a lanyard, and for this reason they are often called keyring readers. The serial reader is a larger device that has several slots which all fit the same type of card. Serial readers are great for people who work with many cards, such as professional photographers.

A multiple memory card reader has several slots and support a wide variety of cards, sometimes as many as thirty different types. They are often called multi-card readers for short, and some manufacturers also call them all-in-one readers. They are great for transferring media between many different gadgets. Multi-card readers typically have fewer slots than supported card types because some slots slots can handle more than one type. This can lead to confusion for buyers who expect there to be the same number of slots as supported types.

There are several features to look for when choosing a memory card reader. An indicator light which flashes when media is being transferred is essential. It helps prevent the reader from being removed before the transfer is complete. The card slots should be spaced out to allow a card to be inserted or removed while there are cards in the slots next to it. The smaller readers should have a ring at one end for a keyring or lanyard because they can easily be lost if they are not attached to something. Readers should also have a connection cable included, along with a driver disc.

The memory card reader is one of the simplest electronic gadgets to use. Anyone who can use a computer, mobile phone, or music player should be able to use a reader. Once it has been plugged in and a memory card inserted, there is often a short wait before the card is detected and its contents have been read. Files can be moved, copied, or deleted from the card just like other files on a computer. Memory cards are quite fast so the transfer speed is often limited by the speed of the connection. It can take a long time to transfer large files to an older computer that has limited connectivity, such as those that do not use the latest USB version.
