The payment page is a web page that allows customers to purchase items easily and securely. As the payment process page illustrates, the payment page pops up when a customer is redirected to an external link to accomplish the payment. As a merchant, the only fields you need to complete a debit or credit card transaction online are the customer's card number, the card expiration date, and the card security code (CVC/CVV). As the process page diagram visually depicts, there are two elements to any payment process. The first involves receiving money from customers. The second involves outbound payments to suppliers, partners, employees, and beyond.
