A computer punched card reader or just computer card reader is a computer input device used to read computer programs in either source or executable form and data from punched cards. A computer card punch is a computer output device that punches holes in cards. Sometimes computer punch card readers were combined with computer card punches and, later, other devices to form multifunction machines.It is a input device and also an output device.Most early computers, such as the ENIAC, and the IBM NORC, provided for punched card input/output. Card readers and punches, either connected to computers or in off-line card to/from magnetic tape configurations, were ubiquitous through the mid-1970s.

Beim Lesen werden die Lochkarten sequentiell zu einer Abfühlstation geführt, wo die als Löcher eingestanzten Zeichen identifiziert und in einen elektronischen Code umgewandelt werden. Zur Verarbeitung unterschiedlicher Lochkartentypen werden/wurden jeweils spezielle Typen von Lesegeräten verwendet. Mitte der 1960er Jahre waren Geräte mit einer Leseleistung von 18000 bis 96000 Karten pro Stunde verfügbar. (de)

Die Verarbeitung von Lochkarten gilt, von Ausnahmen abgesehen, seit Mitte der 1970er Jahre als historische Epoche der Datenverarbeitung. (de)

Card readers and punches, either connected to computers or in off-line card to/from magnetic tape configurations, were ubiquitous through the mid-1970s. Punched cards had been in use since the 1890s; their technology was mature and reliable. Card readers and punches developed for punched card machines were readily adaptable for computer use. Businesses were familiar with storing data on punched cards and keypunch machines were widely employed. Punched cards were a better fit than other 1950s technologies, such as magnetic tape, for some computer applications as individual cards could easily be updated without having to access a computer.
