In many countries the Visa and MasterCard networks have merged so you can use either one of the cards in those countries. However you may not be able to enjoy the same service when you want to withdraw currency from the ATM. You might be able to withdraw on the Visa but not necessarily on the MasterCard. So you might want to carry both your cards while traveling.

There are certain countries that accept both the cards but they have not merged services no you will be required to use both as the case may be, according to the establishment. The Visa and MasterCard are by far the best accepted throughout the world and they are best used while traveling abroad. AmEx and Diners Club are popular in the United States but not so in several countries elsewhere.

Ensure that you check out with your contacts in that country as to what the situation is or you could even go online and garner all the information you need on the credit card acceptance across the world. Beware, there are even some countries that do not accept any credit cards! Yes indeed. So the only way out there would perhaps be to carry cash or travelers checks, if that is accepted that is. However, credit cards are used in most parts of the world today and those places where you cannot use credit cards are not so many.

There are certain countries, which are notorious for credit card fraud. So you have to exercise extreme caution while traveling to those countries and you must try to avoid credit card payments as far as possible. You are bound to get tricked into parting with several dollars if you are not careful or even if your credit card company is not watchful. You might find yourself saddled with a bill that never saw you making the purchase.

When you are traveling abroad, always leave the credit card numbers and a photocopy of the cards along with their phone numbers at home. This will enable you to lodge a complaint in case of fraud or a theft of your cards while you are traveling. It is a precaution well worth taking.
