There are thousands of Walmarts scattered across the country, so it’s no surprise that companies like Apple and Google have been trying to get the supermarket chain to adopt their mobile payments services, Apple Pay and Android Pay, respectively. Unfortunately, Walmart has refused to partner with any of them, and now we know why: it’s launching its own mobile payments service. Going by the uninventive name of Walmart Pay, the new service can be accessed through the Walmart app on either Android or iOS, and can only be used at a few stores in Arkansas, but the company plans to begin an international expansion in the second half of 2016.
