CVV Prompts
CVV prompts are an added security feature to assist in validating a card
against fraud. The V-Code is a 3 to 4-digit number printed on the back
of the card usually to the right of the signature. The CVV is especially
useful for merchants that perform manually keyed transactions where
the cardholder and card is not present to allow for a chip or magnetic
stripe read, usually a mail order or phone (MOPO) order transaction.
When CVV Prompting is enabled during a manually-keyed transaction,
a message prompt asking “Card Present?” will be displayed on the
terminal. If the physical card is not present for the transaction, then
answer
NO . The Terminal will prompt for the CVV (V-Code) of the card;
selecting YES , will bypass the CVV prompt.
Refer to
Section 21 for CVV response codes.
AVS Prompts
Address Verification Services (AVS) are an added security feature to
assist in validating a card against fraud. AVS is especially useful for
merchants that perform manually-keyed transactions where the
cardholder and card are not present to allow for a chip or magnetic
stripe read, usually during a MOPO transaction.
When AVS-prompting is enabled during a manually keyed transaction, a
message prompt will appear allowing a merchant to enter the address,
postal code or both, of a cardholder to perform an address lookup with
the card issuer. AVS will provide a response on the address lookup.
Refer to
Section 21 for AVS response codes.
