Card readers are gadgets that read data from a storage unit that is designed to suit them, i.e. formed into the shape of a card. In the much earlier days of computing, punched cards made of cardboard were used for computer systems' storage as opposed to the storage types we have today. These punched cards were then read by punched card readers. Nowadays, we have devices that rely on magnetic strips, barcodes, and the like for storing data. When people speak of a memory card reader, they usually mean a gadget that is not only capable of reading a memory card but also one that is capable of writing data into it.
