An Ecommerce website is a shopping cart or registration service that processes payments for your business. This includes credit cards, paypal or any other third party web service that can transfer funds to you.
In order to begin doing secure commerce, your website should have a secure certificate. This is what gives your website an encrypted connection from your web host to your visitors’s device. The protocol for this is https. This gives your url a padlock icon in the address bar of the web browser. This tells the visitor that the connection is encrypting the data transferred between their device and your web server.
You also need Ecommerce shopping cart software or services on your web server that will store the information about the transaction in order for you to process the order.
