Traveller's check is a prepaid means of payment that can be used for purchases or cash withdrawals when travelling. Synonyms for traveller's checks include travel cheques, travel money cards, prepaid cards, debit cards, credit cards, foreign currency, and cash. Travel cheques and travel money cards are similar to traveller's checks, but offer additional benefits such as online balance checking and currency conversion services. Prepaid cards are similar to travel money cards and offer the convenience of being able to load the card with a set amount of money before the trip. Debit and credit cards offer the convenience of being able to withdraw cash and make purchases while travelling, but may not always be accepted in all locations. Foreign currency and cash are traditional means of payment for travel, but are less secure and more vulnerable to loss or theft.
