It’s the quickest and easiest shopping solution since self-serve check outs - There just one massive flaw, if the machine on the counter can scan your Pay Pass card details in less than a second then so can one hidden in a jacket or briefcase.
The response from MasterCard about Pay Pass security:
"MasterCard PayPass offers security best practice in the banking industry. Dynamic CVC3, the strongest authentication method, generates a discrete authentication code for each transaction. When Dynamic CVC3 is used, each value is unique by transaction and cannot be reused. Moreover, subsequent values cannot be predicted successfully in a fraudulent environment.
"With a secure chip and radio antenna embedded inside each MasterCard PayPass card or device, consumers benefit from smart card-related security measures. The combination of these security measures and the careful design and choice of specific data that can be incorporated into every PayPass transaction reduces the risk of fraud and makes PayPass
more secure than traditional magnetic stripe cards.
"In addition to the state-of-the-art security built into PayPass, MasterCard cardholders continue to have the peace of mind they have come to expect – knowing that if their card was ever compromised, they are ultimately, as with all MasterCard payment programs in Australia and around the world, protected by MasterCard’s zero liability policy."
