Intelligent Account Verification (IAV)
Intelligent Account Verification (IAV) is a feature to enable you, the merchant, to validate a credit card.
Cardholders submit a zero or nominal value (a payment with a value greater than zero) while Worldpay determine the amount with the best chance of approval. Any value above zero is automatically reversed.
The processing of a nominal value (or zero) is an important part of verifying that an account is real and set up for transactions. Contact Worldpay Support to enable IAV for your company or organization.
