Currency exchange rates are influenced by global financial markets and can change daily or even hourly, affecting the value you receive when converting your home currency. Checking live exchange rates before and during travel informs smart decisions about when and where to exchange. Banks and official currency exchange offices typically offer the best rates and protection against counterfeit money, unlike airport kiosks, hotels, or street vendors, which often add high commissions or provide less favorable rates. Using credit or prepaid travel cards with low or no foreign transaction fees can sometimes offer the best exchange rate available. Being cautious about where and when to exchange funds ensures maximum spending power and reduces the risk of fraud.
