During a transaction, if you feel that a customer, card or transaction is suspicious and needs investigating, call the Moneris Merchant Service Centre and state that the call is a Code 10. This will alert the Moneris agent without alarming your customer. The operator will ask you some "Yes/No" questions and then provide instructions.
Reasons for calling in a Code 10 include:
the signature on the credit card does not seem to match the signature on the receipt.
the card appears to have been tampered with.
the name on the card is inconsistent with the person’s gender.
the customer is purchasing an unusual number of expensive items.
the customer’s purchases seem randomly selected, with little regard for size, quality or value.
the customer seems nervous or signs slowly with uncertainty.
