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.

Purchasing a Product via PayPal Smart Checkout
A customer can add an item to your Simple PayPal Shopping Cart. Once the item appears in the cart, the customer can go ahead and checkout using PayPal Smart Checkout. They can click the button that applies to them.
For example, in the following example, the customer clicks the PayPal button because they wish to pay directly from their PayPal account.
Once a customer clicks on one of the PayPal Smart Checkout buttons, a popup appears where they can complete the checkout process by entering in the appropriate details.
