The easiest way to do a test of your system is to do a small sale (e.g., $1.00), press Save and charge the sale to a live card (don’t press Finalize or you are not able to reverse the charge through the Sales interface, although you could still cancel the charge by calling Moneris). You can then recall the sale and select Tools > Actions > Reverse Payment to reverse the charge. You can also test connectivity by charging to a debit card and entering the wrong PIN which results in an, “Incorrect PIN” response from Moneris if the connection is set up properly.
