American Express Card Security Code Enhancements
In a card-not-present environment, American Express recommends that you include the
following information in your authorisation message:
z Card member billing name
z Postal information (SHIPTO* parameters) such as:
–Address
–Name
– Postage method
z Customer information such as:
– Email address
– IP address
–Host name
– Browser type
z Order information (such as product SKU)
On most cards, the card security code is printed on the back of the card (usually in the
signature field). All or part of the card number appears before the card security code (567 in
the example).
For details on PayPal processor card security code responses, see “Card Security Code
Results” on page 72.
