Less than 5 years ago, the Hongkong retail bank system used to charge about 50 HKD to transfer money online to another local bank. Absolute highway robbery / price fixing. Most absurd: Writing a check was free. Can you imagine the comparative operational cost??? Later, the central bank introduced an free, instant, money transfer system, and forced all banks to join. Paying my rent suddenly dropped 50 HKD per month!

Insane. In the States we have similar gouging with fees when you pay with a card, but some law states that a fee cannot be collected for checks. So I paid rent with a check for the majority of my adult life before Zelle came along even though the option to pay with a card was available.
