Commonwealth Bank customers shopping online with CommBank Checkout will be able to make purchases at more than 200 MasterPass-enabled Australian retailers including; Event Cinemas, The Iconic, Ozsale, and Booktopia - with a simple click or touch of their tablet, desktop or mobile device. Users can pay from a list of pre-stored cards and shipping addresses stored in the digital wallet.

Since the launch of MasterPass in February, MasterCard has formed partnerships with 20 Australian technology partners including both major payment gateways and shopping carts.

By launching the service through a bank partnership, the card scheme says it is giving consumers extra piece of mind when conducting transactions online through their mobile.

"We know consumers prefer the comfort and convenience that dealing direct with their own bank gives them," says Matt Barr, MasterCard's head of market development and innovation, Australasia. "Studies show the connection to your own financial provider is particularly important when it comes to embracing digital payments."

Commonwealth Bank has already advanced its ambitions for mobile payments on the high street with its Kaching app and the roll-out of contactless stickers just last month.

"Commonwealth Bank's focus is to offer our customers the latest technology and innovations that simplify payments regardless of the channel they're transacting in," says Angus Sullivan, executive general manager cards, payments, analytics & retail strategy, Commonwealth Bank. "CommBank Checkout is a convenient and secure way for customers to complete their online purchases in Australia and worldwide which will be particularly handy with Christmas fast approaching."

The service is being launched with a 100% money back guarantee for any fraudulent transactions, he adds.
