Bankers, however, say the fees are the cost of doing business and benefit retailers.
"They are shifting the payment risk and collection cost to somebody else," says Tim Amos, senior vice president and general counsel for the Tennessee Bankers Association.
Retailers, he adds, have options.
They can shop for competing credit card processing companies or pass the cost on to their customers.
On April 10, Steve Kirkham, owner of Kingston-based Rocky Top Markets, told Tennessee legislators his credit card fees reached $130,000 in March. In April 2001, he paid $27,000.
"They are making more on a gallon of gas than I am," Kirkham told the Senate Commerce Committee.
In addition to the rising rates, retailers argue that more customers are using credit cards to combat the increasing gasoline prices, which further increases their costs.
About 70 percent of Kirkham's sales are done with credit cards compared to 45 percent five years ago, he says.
So what are we waiting for? C'mon, Congress. Let's see some action on this front.
