Temkin reviewed 11 companies that issue credit cards and gave USAA the highest score, with a rating of 77 percent. Discover finished second with a rating of 75 percent.
As an industry, credit cards fell slightly from last year's overall ranking. Here's how the various card issuers stack up:
USAA: 77 percent
Discover: 75 percent
Barclaycard: 73 percent
Chase: 72 percent
American Express: 71 percent
Citigroup: 68 percent
U.S. Bank: 68 percent
Capital One: 67 percent
Bank of America: 66 percent
Wells Fargo: 64 percent
HSBC: 52 percent
"In 2017, many of these credit card issuers saw double-digit increases in their scores," said Bruce Temkin, managing partner of Temkin Group. "The fact they managed – for the most part – to sustain those higher scores shows that those gains were not just an anomaly, but actually represented legitimate improvements to their customer experience."
USAA serves the military community, both active duty and retired, along with family members. It offers the Preferred Cash Rewards Visa Signature card, providing 1.5 percent cash back on every purchase.
It also issues the Cashback Rewards Plus American Express card, paying 5 percent cash back on the first $3,000 in gasoline and military base purchases. It pays 2 percent cash back on your first $3,000 in supermarket purchases and 1 percent on everything else.
Temkin says USAA's customer experience score showed the most improvement over the previous year, rising four percentage points. HSBC's score fell the most year-over-year, declining by 17 points.
