Apple, which debuted its payment service in 2014, pitched Apple Pay as a way for people to more easily pay for items at certain retail stores without having to use cash or credit cards. Companies like Best Buy and Staples can also integrate the service into their respective apps so people can more easily buy their products.
Still, not everyone believes that Apple’s online payment system and rival services like Samsung Pay, and Google’s goog Android Pay are growing fast.
In August, Goldman Sachs said in an analyst report that these payment services “have struggled to gain traction,” with one big reason being a lack of compatibility with several big retailers. Walmart wmt , for instance, debuted its own mobile payment system in 2015, thus undercutting the need for it to accept competing payment services.
