Credit Card Processing Overview
The Sun Crypto Accelerator 6000 board supports credit card verification (CV)
processing for the major types of credit cards, Visa, MasterCard, and American
Express. The interface ensures that sensitive customer data is only exposed within
the HSM. The (CV) is a cryptographic checksum of the data stored on a magnetic
card.
Credit card verification is performed during normal ATM and POS transactions to
verify the magnetic card data. The following algorithms are supported:
■
CVV – Visa
■
CVC – MasterCard
■
CSC – American Express
Financial Services Library Function

function requires a valid session handle as the first
argument with the handle parameter. This session handle can be obtained through a
call to
fs_session_open()
. All keys used by these functions must have been
created using the financial services key management functions. See “Key
Management Functions” on page 127 .
The
fs_card_verify
() function enables an application to perform secure card
verification operations. A card algorithm type must be provided in the
alg
argument. The allowable values for the card algorithm type are as follows:
■
CVV – Visa or MasterCard card verification value (CVV) algorithm
■
CSC – American Express card security code (CSC) verification algorithm
