Visa, American Express, Discover, MasterCard – What’s the Difference?

There is certainly no shortage of credit card choices available for consumers. In fact, there are so many choices across credit card networks and issuing banks that it can get downright confusing. Filling your wallet with the right credit cards is a process that’s going to be different for each of us. However, understanding the following regarding the credit card environment can help you make the right choices. First, it’s important to understand the difference between credit card networks and credit card issuers.

Credit Card Networks

The purpose of credit card networks is to control where credit cards can be accepted and to facilitate transactions between merchants and credit card issuers.

There are four major credit card networks:

  • Visa
  • MasterCard
  • American Express
  • Discover

A credit card network sets the interchange or “swipe” fees that merchants are charged to accept a credit card transaction, but credit card networks do not control fees a cardholder pays such as the interest rates, annual fees, late fees, foreign transaction fees and over-limit fees.

Credit Card Issuers

Visa and MasterCard do not actually issue credit cards to consumers. Instead, these two networks have their credit cards issued by credit unions and banks.

Credit card issuers (also referred to as credit card companies) are in charge of:

  • Approving or denying credit card applications
  • Issuing credit cards upon approval
  • Funding the credit limits
  • Setting the terms and most of the benefits on the account
  • Providing customer service.

Although credit card networks and credit card issuers serve entirely different purposes, there is no rule that prevents a company from both processing and issuing credit cards.

American Express and Discover are both credit card networks and credit card issuers.

Credit cards from the Visa and MasterCard networks are issued to consumers by different banks such as Chase, Capital One, Citi, and Bank of America.

American Express and Discover cards are generally, though not exclusively, issued directly from American Express or Discover without the involvement of a middleman.

Credit Card Choices

Though all four major credit card networks are largely accepted by most retailers, a consumer will occasionally come across a retailer or merchant that does not accept specific cards. Sam’s Club, for instance currently only accepts Discover and MasterCard.

When a consumer has credit cards from multiple networks it eliminates usability problems. It’s not a bad idea for consumers to have a credit card from each of the four major credit card networks as long as all of the accounts are managed properly.

It is worth noting that having multiple credit card accounts from multiple networks and/or issuers does not make a consumer more vulnerable or more prone to going into credit card debt. For the responsible consumer there is no bigger temptation to overspend on one credit card versus overspending on four or more credit cards.

Visa vs. MasterCard

Visa and MasterCard are the world’s most popular credit card payment processors, beating out their closest competitors, American Express and Discover. Most people won’t find significant differences between them, but for some lifestyles the choice between Visa and MasterCard might make or break a vacation.

Payment processing networks don’t have anything to do with the interest rates or rewards of a particular card, like points and cash back. These are all determined by the bank or credit union that issues the card, as well as any affiliate companies, like hotel chains.

Instead, the payment network provides some of the auxiliary benefits that often come with cards, like payment protection and auto rental insurance. In our review of Visa and MasterCard we take a look at the particular benefits that each network offers, and what you can expect when you’re a customer.

Today, issuers are offering many cards in either a Visa or a MasterCard version – just call your credit card company and inquire if you’d like to switch »

Global Acceptance

Visa and MasterCard are almost completely comparable here. MasterCard actually states that they are accepted in more countries – over 210, compared to the over 170 countries that take Visa. This might be a difference that doesn’t really make a difference, however, as almost every place that takes MasterCard also accepts Visa. With the growing popularity of both of these networks around the world, it will become increasingly rare to find a merchant that only takes one of these.

Payment Network Member Types

Visa and MasterCard each have 4 general membership types, or service levels.

Visa Service Levels

  • Platinum Visa (basic)
  • Signature Visa (upgraded)
  • Business Visa
  • Professional visa

MasterCard Service Levels

  • Platinum MasterCard (basic)
  • World MasterCard (upgraded)
  • Business Platinum MasterCard
  • Professional MasterCard
