===== AVS Address Verification Service =====

Most payment processors support address verification service. This service checks that the street address and zip/postal code match the address the credit card company has for a billing address.

AVS information in System Five is submitted to the payment processor when the following conditions are met.
  * card is not present - card was not swiped.
  * Customer is attached to the invoice and customer's address is filled in.

System Five will submit the street address and postal code of the Sold to customer.

If the AVS fails to match an indication is shown in the payment authorization screen.\\
The transaction is __NOT__ declined, it is the responsibility of the clerk to check the AVS response on the authorization screen and then void the transaction if they suspect that the transaction may be fraudulent.

The following responses are indicated by the payment processor
