Calculate points. Whether China Merchants Bank credit card has points recognition has nothing to do with VISA or UnionPay channel. It mainly depends on the POS type applied by the merchant. I just traveled in Hong Kong two days ago. I swiped my card to buy things on Canton Road and Nathan Road. I chose UnionPay POS. I checked when I got home last night and found that my points had increased compared to the number before my departure.
In short, whether there are points depends mainly on the type of merchant. Wholesale, real estate transactions, car transactions, public welfare hospitals, and some online payments do not have points. Most physical stores in Hong Kong definitely have points.
