PayPal earlier this year announced a partnership with The Home Depot that allowed customers to make point-of-sale transactions with their smartphones in more than 2,000 locations. The e-commerce company on Thursday announced that 15 new national retailers have signed on for PayPal’s in-store mobile payment service. These include, Abercrombie & Fitch, Advance Auto Parts, Aeropostale, American Eagle Outfitters, Barnes & Noble, Foot Locker, Guitar Center, Jamba Juice, JC Penney, Jos. A. Bank Clothiers, Nine West, Office Depot, Rooms To Go, Tiger Direct and Toys“R”Us. “We can’t wait to launch with these great retailers, and help them serve their customers better through PayPal,” PayPal president David Marcus said. “Consumers are relying on technology now more than ever to simplify their lives when it comes to shopping and paying, and retailers must adapt to this shift or risk becoming irrelevant.” PayPal plans to sign up as many as 20 national retailers this year.
