CBA has circulated a statement supporting its own pre-trial defence against allegations by Austrac that it failed to ensure better risk assessment procedures when it introduced its intelligent ATMs - a claim the CBA accepts for the period to 2015.But then it's become more combative, with this outline of steps taken to improve risk management: "… For example, CBA recently introduced daily limits for IDMs deposits for CBA cards associated with a personal account." This claim was made by CBA several weeks ago, and when asked by Banking Day, the bank added this by way of clarification:"Our understanding is that CBA is the first bank to set daily limits for the amount its customers who are using cards associated with a personal account can deposit in an IDM."For example, our understanding is that a customer at a competitor bank using a card associated with a personal account has no limits on the amount they can deposit each day in that particular bank's IDM. Eg, a different bank customer doesn't have a cap on the amount of money deposited into an IDM each day."This implies the route for money launderers is still open, although not necessarily at CBA. Other banks were not available for comment before this morning's deadline.
