When shoppers “proceed to checkout” from the shopping cart, the transaction shifts to a secure, encrypted channel. A padlock symbol appears in the address bar of the browser, and the URL changes from “http” to “https.”
From this point on, the goal is to gather the information necessary to complete the transaction. The Checkout page leads the customer through each step of the process. Customers who are logged into their accounts can complete checkout quickly, because much of the information is already in their accounts.
