Account Validation (Pre-Authorization)

When you capture payment card data for future use,

National Australia Bank

recommends that you validate the payment card account to ensure that the account number entered is an active, valid account. You can also use the Address Verification Service (AVS), the Card Verification Number (CVN), and expiration date validation. To validate the account, initiate a zero-amount authorization transaction.

If your processor does not support account validation, you can use the minimal supported amount and do a reversal later. You can also enable the

Data Enrichment for Card Verification

feature, which automatically chooses the minimal auth amount. Contact customer support for more details.

For more information about how to perform a pre-authorization, see

Authorization with Customer Token Creation

in the

Token Management Service Developer Guide

.

See the Payments Developer Guide for information about zero-amount authorization transactions.
