I was impressed by the toy-looking screwdriver he used to removed that screw — the design and placement of which looks like is meant to be turned with a coin such as an American quarter.
btw I think one of the reasons why they exist is Japanese coins are thicker than most coin slots. Can be annoying if something is foreign made and I can’t find a penny that fits in desk drawer.
In Japan the standard variety of "coin drivers" are the local equivalent of $4.99 so they can compete with the humble $5 coin.
