You may have noticed that jb02.com is a secure website. It is provided with a certificate which certifies that you are on the site jb02.com and not on a third site. Visually, all pages on the site have a padlock and you will see HTTPS instead of HTTP. By clicking on the padlock above, next to the web address of the page, you'll know more.
Be careful, never make a transaction on a web page that does not include the padlock, certifying that the page is secure.
