This will allow our system to use the card's authorisation data for automatic processing this card for new unpaid invoices. Our system attempt to capture the payment 5 days before the due payment date. Also you can select this saved card when placing a new orders whithout entering a card's authorisation data.
You can enable/disable the automatic card processing in Account Details.
