Banks 'forced to cancel credit cards'

Several banks have been forced to take action and cancel some credit cards following a security breach at a merchant.

Commonwealth Bank, National Australia Bank, Westpac and the St George unit have all had to take the step, with thousands of cards in total being frozen.

The Commonwealth Bank reported that it had to cancel 8,000 cards and has taken measures to inform those who have been affected, with the other financial institutions stating that they had needed to take action on the plastic belonging to a small number of consumers.

"This issue impacts 8,000 customers, but any of these customers that is concerned about accessing should visit one of our branches. We of course will also reverse any fees they may incur as a result of this," CBA spokesman Steve Batten told the Courier Mail.

The use of credit cards was recently an issue for the University of Newcastle, after it was revealed that 1,001 employees with access to cards had spent a total of $19 million last year.  ADNFCR-1761-ID-800560647-ADNFCR
