The primary difference between https:// and http:// is that the “s” in https:// means it’s a secure connection and it is safer to transfer sensitive information between you and the website.
When you are on a site that begins with http:// the communication between your browser and the website is insecure and anyone can see the data being transferred. If you are going to transfer sensitive information such as a credit card number on a website, make sure the website address begins with https://.
For the geeks: HTTP VS HTTPS. Hyper Text Transfer Protocol Secure (HTTPS) is the secure version of HTTP, the protocol over which data is sent between your browser and the website that you are connected to. The 'S' at the end of HTTPS stands for 'Secure'. It means all communications between your browser and the website are encrypted.
