It's hard to say, if it's a public utility, it can't be phased, but undergraduate tuition should not be a public utility. POS machines that pay tuition in schools mostly belong to the merchant codes of correspondence schools (adult education) or other schools and educational services, that is, ordinary merchants can be divided into stages. So it depends on the merchant code on the machine where you swipe your card. If you can see someone else's POS card, the merchant number is 8- 1 1, which means that if it is not 4900, it is not a utility fee.
