after coming to canada and working as a labourer for a few weeks, i worked for the local 'public utilities commission' for a little over two years.
the PUC had decided to adopt a 'punched card system' for meter-reading and billing.
When I first started in 1974, we were required to mark the meter reading in a book of paper cards. The cards were marked with a pencil, much the same way if you were buying a 649 Lottery ticket and chosing your own numbers.
These paper cards would then be put through an optical viewer that would read our pencil marks. If we had rain, it would be terrible for those whose job it was to handle the cards.
Then, later, we were given electronic handheld processors where you would punch in the readings. These processors would be put into a cradle at the end of the day, and the data would be uploaded to the main computer.
They looked a little something like the one below, only more buttons, and a bigger screen, but you get the general idea.

Okay, this is a commercial electric meter that not only measures electric, but also demand readings. We would have to break the seal, and reset the meter every month. The new ones are all digital now.
