You can go to Macau without changing money.
In fact, it is not compulsory to exchange money for traveling to Macao. As long as you bring a credit card, you can also spend it in Macao. At the same time, the exchange rate is automatically exchanged, which reduces many problems.
In fact, it's very convenient to travel to Macao and exchange Macao dollars. There are many banks in Macao, so it is convenient to change money. If you really need money, you can exchange it locally according to actual needs.
At this stage, there is little difference in the exchange rate between the mainland and Macao for Macao, so there is no need to exchange too many coins before going out. You can choose to redeem it, or you can choose to swipe your card directly without redemption.
Personal experience, it is no trouble to change money. Take your ID card and bank card to the bank to change them. At present, banks in some places need to make an appointment at the online bank or go to the bank for exchange before they can get it.
All entry and exit ports have bank exchange windows, which can be directly exchanged for cash. Hong Kong dollars can be used in Macao, while Macao dollars cannot be used in Hong Kong. Hong Kong and Macao can use Alipay, WeChat and bank cards.
More importantly, when changing money in a bank, the exchange rate of the bank is usually more favorable than that of the exchange office, but the queue time is long.
