The World’s Biggest Photo

Losing your wallet used to mean no money.

But with CommBank, customers could now withdraw cash from an ATM without a card using Cardless Cash technology.

Funny thing is, when you can’t find your wallet, you’ll search everywhere for it (even if you have to search an entire city.)

To launch the new service, we took the largest photograph of Sydney ever taken (125 Gigapixel) and hid 100 wallets through the city’s nooks and crannies.

In an interactive game created in HTML5, WebGL and CSS3, users zoomed in and out, panning around the city searching for one of the 10 daily wallets. If they found one, they won a cash prize.

And, of course, the prize money was redeemed through a unique code sent to their smartphone that allowed them to experience Cardless Cash from any CommBank ATM.
