Apple’s head of Apple Pay, Jennifer Bailey, is set to appear alongside other industry titans at Recode’s Code Commerce conference this December. The Apple exec ran the company’s online stores for many years and now leads Apple Pay, Apple’s contactless mobile payments solution.

The Code Commerce meeting takes place multiple times a year; Bailey will be appearing at the last one in 2016 on December 6. No doubt the new MacBook Pro with integrated Apple Pay will form part of the discussions.

Despite her long tenure at the company, Jennifer Bailey’s company presence came into the public eye when she presented at an Apple event for the first time, discussing the latest developments in Apple Pay at WWDC 2015. Bailey has also appeared at previous Recode events.

As part of its earnings call last night, Apple was keen to indicate the exponential growth of Apple Pay. Cook announced that Apple handled more Apple Pay transactions in September 2016 than the entire of fiscal 2015. This represents year-over-year growth of about 500%.

Apple Pay uptake is exploding exponentially as more people become aware of the smart wallet capability in their devices, more people buy newer iPhones and Apple Watch with NFC, and Apple launches the service in more countries.

Apple just rolled out Apple Pay in Japan this week, with Spain set to follow in the “next few months” according to Tim Cook on the earnings call.  The company rolled out Apple Pay to the web with macOS Sierra and iOS 10, helping adoption further.

Apple is holding a media event tomorrow, to introduce a range of new Mac laptops. Per leaks from macOS assets, the new MacBook Pro will include a Touch ID sensor to enable on-device Apple Pay.
