Travel cards are prepaid cards designed for use while traveling, allowing users to load money in various currencies. They can be used for purchases, dining, and withdrawing cash at ATMs, making them a convenient alternative to carrying cash or using credit cards. Many travel cards offer competitive exchange rates and may have lower fees for international transactions. These cards often come with added benefits, such as travel insurance and fraud protection. Popular options include cards from Visa, Mastercard, and specific travel companies like Revolut or Wise. Users can manage their funds through mobile apps, providing easy access to their balance and transaction history.
