Staples shared in an announcement today that it is now accepting Apple Pay transactions at its “over 1,200 stores” in the United States for iPhone 6 and iPhone 6 Plus users. Apple Pay, of course, will also be available for iPhone 5, iPhone 5c, and iPhone 5s users starting next year when paired with the upcoming Apple Watch. Apple included Staples in its list of retail partners when announcing its secure mobile payment service, although Apple noted that support would be “coming later this year” from the retailer as it was [not] available in time for last month’s launch.

Having Apple Pay in Staples brick and mortar stores is a big step for the Apple Pay brand.
