Note: PayPal has deprecated the Smart Checkout feature. Switch to using the PayPal Commerce Platform (new API) which replaces the Smart Checkout option.
The PayPal Smart Checkout is an option you can enable in your WP Simple Cart Plugin. The Smart Checkout Button provides your customers with an alternative checkout method. The PayPal Smart Button Checkout contains a number of buttons that allow your customers to checkout using their PayPal Account, their credit card (Visa, Mastercard), Buy Now Pay Later or PayPal credit.
The checkout form is displayed to the customer in a popup window.
