PROTECTING YOURSELF ONLINE Credit Card Safety Make sure the site uses encryption. If you don't see a closed padlock icon in the bottom of your browser, don't shop there. Shop at reputable on-line stores. If you've never shopped at a site before, check their reputation at the Better Business Bureau's site. Don't let sites store your information. Many stores give you the option to store your credit card details, so you don't have to re-enter your information every time you shop. If they ask, just say no.
