A foreign currency exchange machine is an automated financial device that allows users to exchange one foreign currency for another. These machines are typically located in areas with high concentrations of foreigners, such as airports, hotels, tourist information centers, and business districts, to provide convenient foreign currency exchange services for tourists and multinational workers. Foreign currency exchange machines usually have the following functions:

1. **Currency Identification**: The exchange machine can identify various foreign banknotes and coins and count them.

2. **Exchange Rate Display**: The exchange machine displays the current exchange rates, allowing users to decide whether to make the exchange based on this information.

3. **Exchange Operation**: Users follow the prompts on the screen or the instructions to select the type and amount of currency to exchange, then insert the corresponding foreign banknotes or coins.

4. **Change Giving**: If there is a remainder after the exchange, the exchange machine usually provides change.

5. **Security Measures**: To prevent fraud and crime, foreign currency exchange machines are often equipped with security locks, surveillance cameras, and other security features.

6. **Data Recording**: The exchange machine records data on exchange transactions, including the type of currency exchanged, the amount, and the time, for subsequent auditing and management.

7. **Network Connection**: Some advanced foreign currency exchange machines can be connected to the internet for remote data transmission and equipment maintenance.

8. **Multilingual Support**: To serve users who speak different languages, exchange machines may offer multilingual interfaces.

The emergence of foreign currency exchange machines has greatly facilitated the need for currency exchange between countries, saving time and costs, and also provides a more flexible exchange schedule and service than traditional bank teller counters.
