This module adds a paypal checkout button to the shopping cart and create account pages.This allows a customer to quickly checkout since they don't have to go through the regular checkout process. The customer is edirected to PayPal to make the payment and then returned once the payment is made. An account will e created for them if they do not already have one, thus saving more time. Some shops report problems with payments made with mobile devices when using this module. The Paypal App module is not prone to that problem and is the one we recommend for most shops.
