A punch card machine operates by creating holes in a card to represent data or commands, which can then be read by a corresponding machine. The user inserts a blank card into the machine, and a series of mechanical or electronic components punch holes based on input instructions. Once punched, these cards can be processed by a reader that detects the presence or absence of holes to interpret the encoded information. This system was widely used in early computing and data processing before the advent of more advanced technologies.
