This certainly isn’t the first time we’ve seen an attempt to bring NFC to the iPhone, but the Commonwealth Bank of Australia certainly deserves kudos for integrating the iCarte case with its mobile payment app known as Kaching (think Ka-ching). Available as a standalone free application, Kaching allows users to send money to others, either via text message, email or through Facebook. For those looking to dig deeper, an iCarte case may be purchased for $ 54.95 from within the app, which allows the iPhone 4 and 4S to be used for mobile payments at all PayPass terminals. From within Kaching, users may check account balances and choose which card they care to pay with. All in all, it looks like one sweet (albeit temporary) solution.
