Why you should carry a backup credit card while traveling

The average American has four credit cards, according to Experian, the credit reporting agency. However, travel rewards enthusiasts may differ slightly from the average American regarding credit cards and may carry more than four cards. But if you’re new to points and miles or just taking it slowly, you may not have a wallet full of credit cards.

Whether you’re above, below or on average regarding the number of credit cards you hold, you probably don’t bring them all with you while traveling. But have you ever thought about how many you should bring and what types?

Let’s dive into why it’s important to travel with at least two cards and some best practices for your backup card, whether you’re traveling within the United States or internationally.

There are four major credit card networks in the United States: Visa, Mastercard, American Express and Discover. Credit card networks facilitate transactions between a merchant and an issuer. Some, such as American Express and Discover, are both a network and an issuer. On the other hand, Visa and Mastercard are only networks and have various issuers. If you have a Visa credit card, it will be issued by a bank, such as Chase or Bank of America, whereby a Mastercard credit card could be issued by Citi or Wells Fargo.

Visa and Mastercard credit cards tend to be widely accepted in the United States and abroad; American Express and Discover are less so, especially abroad. Suppose your primary or everyday spending card at home is an Amex or Discover. In that case, bringing a Visa or Mastercard while traveling is a good idea if you encounter merchants that do not accept Amex or Discover. And in the rare instance that a network suffers an outage and you can’t make any purchases, you’ll be able to switch to a backup card on another network.

You may also need another card in cases where your primary card is lost, stolen, declined or locked due to a fraud alert. If possible, your backup should be a card from a bank different from your primary card.

Worst-case scenario, if a bank or issuer flags your accounts for suspicious activity and locks all of your accounts while traveling, you can switch to a card from a different bank. But if all of your cards are from the same bank, you’ll be out of luck until you’re able to clear up the issue with your account, which could get problematic if you’re in the middle of a transaction, in a time crunch, or unable to contact your bank.

Some travelers even go as far as keeping a second, or decoy, wallet. Some carry a decoy wallet with a small amount of cash, and some closed or expired credit cards to fool a mugger or pickpocketer if an unfortunate incident occurs. Others use a second wallet to carry around just the card they need for the day, while the main wallet and other cards remain safe in the hotel room.

With the growing acceptance of mobile payment methods (such as Apple Pay and Google Pay), even internationally, you may also want to add multiple cards to your mobile wallet. You or a merchant may still prefer to use the physical card, but at least you’ll know the mobile wallet option is there in a pinch.

Sure, but if any are lost or stolen, it could be a big headache as you’ll make many phone calls to cancel cards. And who wants to spend their vacation doing that? It’s understandable why you may want to bring a variety of cards if you’re trying to maximize rewards by using multiple cards for different spending bonus categories on your trip, but keep at least one card back in your hotel room safe.
