Mailorder Transactions (Customer Not Present)
You must ensure that this option is enabled on your acquirers
Merchant Account.
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.
For American Express cards there is 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.
