If the merchant has a UnionPay POS, it will exchange RMB for Canadian dollars, and will automatically purchase foreign exchange in RMB for repayment after returning home, without charge.
If the merchant only has MCPOS, he will change US dollars into Canadian dollars to continue spending, and MC will charge 1. 1%- 1.5% as the exchange rate procedure, and will automatically purchase foreign exchange in RMB for repayment after returning home.
Different banks have different MC card rates. There will be a difference of 1. 1%- 1.5%. The purchase price of foreign exchange will not be displayed in the bill, but will be displayed in the bill together.
