Memory card reader: use
The memory card reader, also called a flash card reader, allows you to read the different memory or flashcards found in cell phones, cameras, or GPS devices.
Your computer may integrate a memory card reader. Still, if it is not the case or does not propose compatibility with all the memory cards, it is possible to get an external memory card reader.
The external memory card reader plugs into one of the computer’s USB ports.
