The IBM 1402 was a high-speed card reader/punch introduced on October 5, 1959 as a peripheral input/output device for the IBM 1401 computer. It was later used with other computers of the IBM 1400 series and IBM 7000 series product lines.[1][2] It was adapted as the IBM 1622 Card Read-Punch for the IBM 1620[3] and provided the basic design for the models 2501, 2520 and 2540 equipment used with the IBM System/360 product line.
