Significance

• Due to the amount of travel people do to other countries, an exchange system allows people to always have the proper, local currency. If a person does not have the right currency in a country, most vendors will not allow the person to buy products with a separate currency.
  
  

Rates

• The exchange rate is the amount one currency trades for exchange in another currency. For example, an exchange rate might be $1 for €1.25. The exchange rate constantly changes, so you should keep abreast of current exchange rates before you exchange your money to ensure you receive the proper amount.
  
  

Fees

• When you exchange small amounts of currency, for example $20, most foreign exchanges add an additional fee to the exchange. This helps them gain profit and helps reduce risk of losses due to changes in the currency. If you exchange large amounts on a regular basis, usually as an investment strategy, the foreign currency exchange typically waives the fee.
