Credit cards designed specifically for use abroad are particularly beneficial to those who travel a lot, and want to avoid incurring extra charges when they use their credit card on vacation. Travel cards can give you access to free cash withdrawals at overseas ATMs, as well as better rates on your travel money, reward points for flights, and sometimes even discounts on travel insurance. Additionally, some travel cards will not charge any extra for making purchases overseas in a foreign currency, or when you buy products from overseas websites.
