Have you ever clocked on? I did for a few weeks one summer when I got a holiday job. The clock machine we had to use was a big grey box with cards in slots next to it.
I also clocked on for an art project. Each time I went into my studio I clocked on, and off. The cards were collected and turned into an artwork later on.
So seeing this at the museum rang a bell… Some forty year old thought woke up and reminded me of a dirty grey factory floor, oil splashed on the machines, knurling air filters for cars (joining the concertinerd paper together) with two clogged wheels that pressed the ends together to hold them in place before they had cages and the rubberised circles fixed to the top and bottoms, then clock off and go home at the end of a long, boring day. So clocking on? I’ve done that.

The good ol’ Bandy clock! Yes, I have, when I was an undergraduate!

I beg your pardon, it’s Bundy, not Bandy lol that’s what those things were called where you insert the paper/card and it records the time 😁

Did some search. Apparently, the first one was invented by a jeweller called Willard le Grand Bundy in 1888. Time clock in general terms, but I also remember it being referred to as punch clock 😁
