Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A punched card reader or just card reader is a computer input device used to read data from punched cards. A card punch is a output device that punches holes in cards under computer control. Sometimes card readers were combined with card punches and, later, other devices to form multifunction machines. Many early computers, such as ENIAC, used punched card input/output. When IBM entered and began to dominate the computer industry starting in the early 1950s, it used the punched card for programming, data input and often for data output. IBM had been leasing punched card based unit record equipment for over half a century by then and its technology was mature and reliable.
