If you thought you were leading the way doing a spot of banking from your smartphone and not your computer or at the teller, think again, as Westpac shows what’s possible when you have a smart watch.

Made available for our friends across the puddle in New Zealand, the app has been built by Westpac NZ, and is a piece of software for the Sony SmartWatch that has yet to be released in Australia.

Based on the Cash Tank app which the bank released in that country last year, this piece of software will run on the Sony SmartWatch and let customers of the bank access their account balance without needing authorisation, which given the position of the watch – a wrist – could give customers a much needed advisory right before they’re about to bring out the credit card.

“Customers are adopting all forms of mobile technology at an extraordinary pace,” said Simon Pomeroy, Head of Digital at Westpac in New Zealand.

“We see this development as another step forward and a key part of our strategy to offer them the best digital banking experience in New Zealand with unparalleled functionality across all devices.”

The app isn’t available yet, but Westpac has already started working on more functionality for the app, with it possibly supporting more smart watches later on.
