Walmart's Payment App Can't Compete With Apple Pay

NEW YORK, NY - OCTOBER 20: Apple Pay is promoted on signs placed at the cash register of Whole Foods in Columbus Circle on October 20, 2014 in New York, NY. The software, which debuted today, is available in the recently updated iPhone 6 software and accepted in 220,000 stores. It allows iPhone users to pay for purchases using their iPhone's NFC capabilities instead of using their credit card. (Photo by Bryan Thomas/Getty Images) Bryan Thomas—Getty Images
