Loraine Mullen-Kress carries a Bank of America credit card and religiously pays off her balance.

“Flawless credit,” she boasted.

“There is a big segment of their population that they will have never made money on, which is people who pay their bills on time every month,” said Ben Woolsey, Director of Consumer Research at CreditCards.com.
