Earlier quoted context omitted.
When you give someone a physical check, you are giving them your bank account info. It is written on the bottom of every check.
People outside the US stopped using cheques ~decades ago. At 40+ from New Zealand I've literally never paid anyone with one and have been paid with them only a handful of times.
Oddly, given the context of this thread, the UK is an exception. Or at least it was until a few years ago (I left in 2019). They have Faster Payments, but they also still use (used?) cheques more often than any other non-US country I've interacted with. For example, a number of UK universities still do (or until recently did?) expense reimbursements in the form of paper cheques, when reimbursing people not employed by the institution. One university even mailed a paper cheque, made out in British pounds and drawn on a UK bank, to our French invited speaker! The speaker found it inconvenient/expensive to have to deal with that, but their bank was fortunately able to figure out how to deposit it.
