credit card
Many hotels, shops, restaurants and hotels in Phnom Penh, Siem Reap and other cities accept payment card checkout services (such as visacard and mastercard).
Tips:
1. It is sometimes convenient to change more change, such as 65438 yuan +0. Generally, local people don't accept paper money above 10000 riel. When local people give you large change after shopping, they will accept dollars.
2. Hong Kong dollars, Australian dollars, Singapore dollars, Japanese yen and Thai baht can also be exchanged, but it is not as convenient as US dollars, and it is not easy to exchange RMB for local currency, so don't carry too much RMB.
3. Try to use up Cambodian currency before the end of the trip, because other currencies cannot be exchanged outside Cambodia. But it's not bad to be a commemorative coin.
