Card reader

A card reader comprising:

• a housing;
• a first port compatible with USB, the first port being disposed on the housing and being adapted to insert into a USB connector;
• a second port compatible with PCMCIA, the first port being disposed on the housing and being adapted to insert into a cassette connector compatible with PCMCIA;
• a slot disposed on the housing, the slot being adapted to receive one of a variety of memory cards;
• a circuit board within the housing;
• a first interface module compatible with USB, the first interface module being disposed on the circuit board;
• a second interface module compatible with PCMCIA, the second interface module being disposed on the circuit board;
• a data conversion module disposed on the circuit board, the data conversion module being selectively coupled to the first interface module or the second interface module and being coupled to the slot for converting data stored in the memory card into a read/write form of the first interface module or the second interface module;
• and
• a control module disposed on the circuit board, the control module being coupled to the first interface module, the second interface module, and the data conversion module wherein when the control module either detects a connection of the first port and the USB connector the control module couples the data conversion module and the first interface module together, or detects a connection of the second port and the cassette connector the control module couples the data conversion module and the second interface module together.
