Now, the company appears to be hiring for two new senior electronic payments positions, according to Re/code.
Citing anonymous sources, Re/code writes that Apple is looking to fill positions for head of product and head of business development.
"Their ambitions are very, very serious," one of the sources told Re/code.
Apple already lets hundreds of millions of users buy music, books, and apps through an iTunes account linked to their credit cards. So, expanding this payment process into a digital wallet, or some other sort of mobile payment service, could be a feasible shift for the company.
In January, it was rumored that Apple was exploring a move beyond the digital realm into letting users pay for physical goods and services -- such as clothes or a taxi ride -- with an iTunes account. Reportedly, Apple has been conducting on-going meetings with industry executives to discuss the topic.
Expanding into a mobile-payments business could put the company in direct competition with services like Stripe and eBay's PayPal. According to Re/code, there's the possibility that Apple could even partner with PayPal in some sort of joint payment system.
CNET contacted Apple for comment. We'll update the story when we get more information.
