Temporarily increasing contactless ‘tap-and-go’ card limits

A temporary increase to the contactless ‘tap-and-go’ limits, from $100 to $200, will be progressively rolled out nationally from April 2020, is being introduced to help reduce the spread of COVID-19. This change is supported at an industry level by the Australian Payments Network.

What do you need to do?

You don’t need to do anything. When the functionality is available on your terminal and the cardholder’s card, the terminal will no longer prompt the cardholder to enter their PIN for contactless transactions under $200.

For more information, please refer to the FAQs.
