The Commonwealth Bank of Australia has released its latest CommBank app for iOS devices, following its launch on Android and Windows Phone platforms late last year. The new version of the app introduces a host of new features including a redesigned user interface and contactless NFC payments via an optional ‘PayTag’ sticker. The new CommBank app’s main claim to fame is near field communication (NFC) ‘Tap & Pay’ functionality, which allows customers to make instant MasterCard PayPass payments with their iPhone. This requires the customer to purchase a CommBank ‘PayTag’ NFC sticker ($2.99) which attaches to the back of your phone. Users can then use the PayTag sticker to make contactless payments up to $100 by simply tapping their phone. (By contrast, the Samsung Galaxy S4 (i9505 and i9507) has Tap & Pay built directly into the app via their phone’s embedded NFC chip). The CommBank app is available now from the App Store. It is also still available from Windows Apps+Games and the Google Play Store.
