The punched cards is made of cardboard sheet containing information in the form of perforations in a binary code. These were the first methods used to enter data and instructions into a computer in the 1960s and 1970s. Punch cards were used previously by Joseph Marie Jacquard in his invention, the automated loom. They were then used in the first electronic computers by companies such as IBM, NCR, Burroughs and others.
