QY - Card type not accepted
The Merchant is not enabled for the particular Card Scheme (normally returned for American Express® and Diners Club cards). To register for American Express® or Diners Club, click the Register to accept Amex or Diners through PayWay link on the Merchants page. Note: There are no response codes specific to card verification number mismatches. This is because no financial institutions in Australia currently return any such information if declining a transaction.
