What are aperture cards?

Although you’re likely familiar with this medium, they’re currently rare enough that a brief description of their purpose and function is worth noting.

Aperture cards were first put to use for their current purposes in the mid 20th century. Their adoption accompanied the rise of early computers, which were designed to process the data contained on the cards. Like other microfilm, aperture cards are purposed to compress data into a smaller format, making duplication and transfer easier than it would be if data remained full-sized.

They do this through a series of physical hole punches representing coded data. Additionally, the cards contain miniaturized microfilm chips, allowing for image storage.

For decades, these cards were the preferred method of data storage for many industries due to their ability to be easily read, indexed, stored and quickly retrieved by computer.
