The biggest security breach at a credit card data processing center in US history could affect as many as 127,000 Australian card holders, according to ABC radio.
CardSystems Solutions in Arizona has seen the theft of private information on more than 40 million credit card holders around the world, and in Australia, about 50,000 Mastercard and another 77,000 Visa card holders are believed to have been at risk, ABC radio reported.
However, these irregular transactions were picked up as early as December, and banks say that most of those affected have already received new cards.
“We’ve been through a process over the last six months of alerting the Visa and Mastercard schemes in our region and in the US about the issue,” a spokesman for ANZ Bank, Paul Edwards, told ABC.
