Commonwealth Bank of Australia has launched an online virtual treasure hunt, challenging customers to scour through a detailed panoramic photo of Sydney to find one of ten yellow wallets hidden in secret locations across the city.
The bank worked with Pixelcase to take 8000 shots of the city from Sydney Tower to create one mega 120 gigapixel image, which customers are invited to swoop around and zoom in as they search for the hidden wallets.
The virtual treasure hunt is being used to promote the bank's mobile Cardless Cash app that enables customers to make ATM withdrawals up to a maxmimum of $200 per day using just their smartphone.
Jessica Meyers, CommBank executive marketing manager, says: "For us, it's really great to have taken the largest image ever in Australia. it really pushes the boundaries in terms of technology, which is a big focus for the bank."
