Your terminal is pre-configured for mailorder (Customer Not
Present) transactions.
Mailorder transactions are performed without the customer or
the card being present. All card details must be manually
entered so please take note of what information will be asked
for by your terminal.
If supported by your acquirer and by the card type taken, you
will have the option of entering the CSC (Card Security Code)
and using the AVS (Address Verification Service).
The CSC is the last three digits of the number printed on the
signature strip on the back of the card.
American Express cards have a four digit Card Security
Code printed on the front of the card, any numbers on
the signature strip should be ignored.
To use AVS checking, you will be prompted to input the
numerical digits only from the customer’s postcode and
address. The response from the acquirer will then give you the
result of the security checks to help you decide if you wish to
continue with the transaction.
