Introduction To The Card Reader

Card-reader refers to an interface device used to read and write multimedia cards as a mobile storage device in a computer. The commercial version of the card reader can read security smart cards. The card reader is usually connected by USB and can access a variety of formats of memory cards, such as CompactFlash and Secure Digital. When the memory card is matched with a proper card reader, it can be used as a normal flash drive. In addition, some printers have integrated card readers. Users can easily use the printer to print out the photos.

Some card readers can only access one type of memory card, while others are all-in-one card readers. Some memory cards have integrated the function of a card reader. Users only need to insert the memory card into the USB socket, and the computer can access the data in the memory card in real time.
