Standard Bank: Convict

When people pay for stuff on the credit cards, very rarely do they really pay attention to what the cashier is doing. If, however, the person behind the till looked like a classic criminal, they'd probably pay a lot more attention and want the extra security they can get from the chip and pin technology. Using humor, TBWATequilaJohannesburg identified this behavior and highlighted that most criminals don't look like criminals, which is exactly why chip and pin technology is needed.
