China Union Pay debit cards were used to purchase gambling chips at The Star casino in Sydney for several years, in prohibition of the card issuer's rules.
Formerly Star's main point of contact with NSW regulators, current group compliance manager Graeme Stevens knew they were being used to gamble but he says the first he heard of it being prohibited was at the start of an inquiry into whether the casino should keep its licence, which he appeared at on Thursday.
He was then presented with several documents dating to 2013 suggesting otherwise: that in fact The Star knew the cards were not to be used for gambling and sought to get around that.
