Apple is considering launching a mobile-payments service for its iPhone and iPad, which would compete with major players such as PayPal, The Wall Street Journal said Friday. The newspaper, citing sources familiar with the matter, said Eddy Cue, Apples iTunes and App Store chief, has met with industry executives to discuss Apples interest in handling payments for physical goods and services on its devices. Apple manages purchases of digital content in its online store iTunes. Consumers can also buy mobile applications using their iTunes account, meaning the company already has hundreds of millions of credit cards on file.
