Pizza Hut recently had an activity to swipe the Bank of Communications credit card, which was reduced 120. When swiping the Bank of Communications credit card, the clerk said that he had to pay the full amount. That's not true. When swiping a card, you need to use the special POS machine of Bank of Communications. Swipe a qualified credit card and directly subtract 19.99. For example, if you spend 120, it is actually 100.438+0. You just need to read the documents printed by POS carefully, and you can't use other POS machines to brush them, because that won't reduce the money. I hope my answer is helpful to you. thank you
