The currency in Vietnam is the Vietnamese Dong (VND). As of February 2023, the exchange rate will be converted into Vietnamese (VND) according to the Vietcombank exchange rate.

When traveling to Vietnam, it is recommended to bring cash in USD or other major currencies to exchange at banks or authorized exchange offices. Major credit cards are also accepted in some hotels, restaurants, and shops in larger cities, but it is still advisable to carry cash for smaller transactions and when traveling to rural areas.

ATMs are widely available in Vietnam, especially in urban areas, but it is important to check with your bank about any international fees and to inform them of your travel plans to avoid any issues with accessing your funds.

Be aware that some places may not accept large denominations of Vietnamese Dong, so it is advisable to have smaller notes and coins on hand. Additionally, it is recommended to exchange money at official exchange offices or banks rather than with street vendors, who may offer better rates but may also be engaging in illegal activity.

In Vietnam, cash is widely accepted and preferred for small transactions, especially outside of major cities. However, credit and debit cards are becoming increasingly accepted at larger retailers, hotels, and restaurants. ATMs are also widely available in urban areas and tourist destinations, where you can withdraw Vietnamese Dong (VND) using your debit or credit card. Some international banks such as HSBC, Citibank, and Standard Chartered operate in Vietnam and have branches and ATMs available for use. It's always a good idea to notify your bank or credit card company of your travel plans to avoid any issues with transactions being declined due to suspected fraud.
