The IBM 2540 is a punched-card computer peripheral manufactured by IBM Corporation for use of System/360 and later computer systems. The 2540 was designed by IBM's Data Processing Division in Rochester, Minnesota, and was introduced in 1965. The 2540 can read punched-cards at 1000 cards per minute (CPM) and punch at 300 CPM. The 2540 is based on the design of the older, slightly slower, 1402.
