Fraudulent and lost/stolen cards are a threat to us all. Even if the card swipes and you get a signature, you may still be financially liable for fraud. If you are ever suspicious, either by the customer's behaviour of the card itself, call Moneris to report a Code 10 authorization. You will be transferred to the card's issuing bank to answer a series of yes or no questions. Take a look at our Fraud Protection page to protect yourself, your employees and your customers from fraud.
