The new companies that recently agreed to work with the service include SunTrust, Barclaycard and USAA. Ten more banks, including TD Bank North America and Commerce Bank, will back the new form of payment on Tuesday. With the new additions, Apple says it supports the cards that represent about 90 percent of the credit card purchase volume in the United States.
The New York Times notes that Staples now supports Apple Pay at 1,400 U.S. locations. Winn-Dixie and Albertsons grocers also accept the payment method. Whole Foods says it's already processed more than 150,000 Apple Pay transactions.
Apple Pay has also seen good traction with other businesses including McDonald's who says Apple Pay accounted for 50% of its tap-to-pay transactions in November.
Although the service currently accounts for a tiny fraction of total transactions it's already doing better than any of its competitors and usage is increasing.
