Abu Dhabi Police GHQ - E-commerce Security

Before you buy anything online make a note of the address of the company that you are buying from. This should include details of the telephone and/or fax - never rely on just an email address.
Always use secure sites, These sites have 'https' in front of the web address which indicates that the company has been independently checked to make sure they are who they say they are. A yellow padlock symbol will appear in the browser window to show the payment process is secure.
When transferring money use reliable firms.
Never transfer or receive money for someone else you don't know well.
Check the sites' privacy and returns policy.
Print out a copy of your order and any acknowledgement you receive.
Check your bank statement carefully against anything you buy online.
Keep your passwords secure.
It's always preferable to keep a separate credit card for online usage with a limited account balance.
Make sure to report any theft or assault you face internet fraud.
