The Vietnamese Dong (VND) is the official currency of Vietnam, introduced in 1978. It is identified by the ISO 4217 code VND and is commonly represented by the symbol ₫. The State Bank of Vietnam (Ngân hàng Nhà nước Việt Nam) is responsible for issuing and managing the Vietnamese Dong. Currently, circulating Vietnamese Dong banknotes include denominations of 100, 200, 500, 1000, 2000, 5000, 10,000, 20,000, 50,000, 100,000, 200,000, and 500,000 Dong, along with coins in denominations of 200, 500, 1000, 2000, and 5000 Dong. Although the Vietnamese Dong is not a mainstream trading currency, Vietnam has consistently been a popular travel destination for Hong Kong. The majority of local money changers facilitate the buying and selling of Vietnamese Dong.

港幣（HKD）是香港特別行政區的流通貨幣，首張港幣由東方匯理銀行發行於1845年，距今已經超過179年。港元採用聯繫匯率制度，最初與英鎊掛鉤，但1972年6月英鎊改為自由浮動制後，港府決定將港幣改為與美金掛鉤，並延續至今。港府設定的浮動範圍在1美金兌7.75到7.85港元之間，如果匯率超出此范圍，金管局將出手干預，以維持穩定。在本港的找換店行業，港幣最經常兌換的外幣包括人民幣、日元、菲律賓披索、印尼盾以及美金。
