While driving through Jakarta, I passed a sign saying ATM. I used ATMs around the globe countless times, but I never asked myself what ATM actually stands for.

My first thought was “Automated Transaction Machine”. My second thought was, transactions are triggered my humans, thus, they’re not automated. Then, I thought that ATM might stand for “Atomic Transaction Machine”.

I decided to stop guessing around and look it up. And, to my surprise, the acronym ATM stands for “Automated Teller Machine”.
