Interesting fact: the Hollerith punched card is the same size as the dollar bill in 1890. This is because Hollerith was able to take advantage of existing stacking and sorting equipment already designed for banks.

- kens 10y agoStrangely, punched cards are just a bit bigger than the old US currency, not exactly the same size. Also strange: nobody knows exactly how big the old currency was. To be precise, there are three slightly different sizes quoted as the official size. I asked the Bureau of Engraving and Printing about this - they print the money so they should know - and they couldn't explain the discrepancy.
