'Duì diǎn' literally combines 兑 (duì), meaning 'to exchange' or 'to convert', and 点 (diǎn), meaning 'spot', 'place', or 'point'. Together, it refers specifically to a physical location where currency exchange takes place — such as a bank counter, airport booth, or hotel front desk designated for converting money. It emphasizes the *site* of exchange rather than the act itself.

This term is commonly used in travel, finance, and daily life contexts involving foreign currencies. You’ll see it on signs (e.g., '外币兑点'), in announcements ('请前往3号兑点办理'), and in service descriptions. Unlike the verb 兑换 (duìhuàn), which means 'to exchange' as an action, 兑点 names the *place* — similar to how 'ATM' names a machine, not the withdrawal process. It’s neutral in register and widely understood across Mainland China, Taiwan, and Singapore.
