Points of View: Will my rewards change if I pay by mobile wallet?

Here at TPG, we regularly emphasize maximizing your earnings on each purchase. For example, we recommend using these credit cards at supermarkets and paying with these cards when at the gas pump.

But what if you use a mobile wallet — such as Apple Pay or Google Wallet — to pay for purchases? Will your "great for supermarkets" credit card still earn bonus points or cash back, or will that purchase code as something else, forfeiting rewards?

Let's examine whether your rewards will change if you pay by mobile wallet.

What is a mobile wallet?

Before we jump in, let's clarify what a mobile wallet is.

A mobile wallet is a smartphone app that holds things like credit cards, gift cards and mobile boarding passes for a flight. You don't need to show your physical credit card when paying with a mobile wallet. Instead, you hold your device near the payment terminal and make payments that way.

Mobile wallets can be useful for those who carry multiple credit cards, as you'll have the ability to use them without the bulk of carrying them in your physical wallet.

Most credit and debit cards can be used with mobile wallets. However, there are exceptions.

You can't add ATM-only cards. You also can't add corporate credit cards from most issuers or small-business credit cards from Bank of America.

Know, too, that you might receive an error when adding a new card since your mobile wallet may need time to complete a security review on your newly-activated card.

What rewards will you earn from mobile payments?

The good news is that mobile wallet payments at a supermarket should still code as a supermarket expense on your credit card statement, earning whatever rewards your card provides for supermarkets. That's because the Merchant Category Code — which stores set to identify their business type — stays the same. The MCC on your payment shouldn't change whether you swipe your credit card or pay with that same card through your phone's mobile wallet.

However, note that I said "shouldn't." You may sometimes see strange coding on these kinds of purchases. For example, two TPG employees had recent mobile wallet purchases at Walgreens, Rite Aid and CVS code as "merchandise."

I also ran into a unique situation while living in Brazil for nearly six years. Most businesses in Brazil that accept American Express cards use a separate credit card machine for these payments. Because of this, they classify the second payment terminal differently than the first.

For example, a restaurant will have a credit card machine for Visa, Mastercard or Discover payments; as the primary credit card machine, it's assigned a "restaurant" MCC. The Amex terminal is assigned a "bar" MCC to separate the payment-processing machines. That means these payments don't earn bonus points in a restaurant category.

TPG points and miles reporter Kyle Olsen had the same experience when visiting Brazil last month. When paying with Amex cards, he didn't earn bonus points at restaurants.

Barring these abnormalities, most mobile wallet payments earn how you would expect: Supermarkets are supermarkets, gas is gas and taxis are taxis. A credit card with bonus-earning rates in those categories should provide the associated benefits.

Credit cards with bonus earnings for mobile payments

Some credit cards award bonus points when making mobile wallet payments, regardless of your purchase. You could make a mobile wallet payment at your corner store or local mechanic and earn bonus points in this category, regardless of your card's other earning categories.

There aren't many cards that earn extra rewards on mobile wallet payments. However, they can provide serious value when you compare the mobile wallet earning rates to everyday earning rates for swiping your card the old-fashioned way. Here are some top ones:

For everyday spending (in which you won't earn any bonus points or cash back), changing your payment method could lead to hundreds or thousands of dollars in extra value at the end of the year.

Bottom line

In most situations, paying by mobile wallet should net the same rewards you'd receive by swiping your physical credit card. However, there are some exceptions.

There are a few cards that provide bonuses on mobile wallet payments. Additionally, there are times when you might earn according to your card's everyday spending category. As a result, it's important to double-check your cards' fine print to make sure you maximize your earnings — whether you pay the traditional way or via a mobile wallet.
