AN ESTIMATED £1.2million was stolen from borough residents in the last year - by way of stolen cash and credit card details and internet transactions.
Figures just released show there were 685 offences and 1,623 victims - but police say this could be dramatically cut if people were better educated about the risks of using credit cards.
Detective Sergeant Tony Mitchell, of Hillingdon CID, is leading the campaign by trying to boost awareness of the problem.
He said: "Free money - this is what a modern-day fraudster is thinking every time he wakes up in the morning.
"How easy is it to get hold of someone's card details? How careful are you when it comes to securing your information?
"Let's say, for example, you order a takeaway for delivery and pay on your card. What details have you given them? Name, address, card number, expiry date, security code. How easy was that?
"The same can be said for ordering items over the internet or the telephone. How well do we know the person on the other end of the line?"
In 2008 there were losses of more than £608m in the UK. The two biggest areas of fraud were transactions not protected by chip and PIN and card offences abroad.
DS Mitchell added: "First and foremost, be sure that details you give out are going to a trusted site, a well-established chain of shops, known persons that you may have had dealings with before and secure web pages.
"Be careful as some fraudsters use fraudulent pages, which look like PayPal but aren't. One noticeable difference is the spelling. I have noticed one called 'PayPall'.
"Fraud scams are being committed over the internet at an alarming rate on sites such as eBay, Gumtree, Autotrader and the likes. All these sites have fraud investigation teams looking at the adverts, but sometimes bogus ones slip through their nets.
"Never pass details of any transaction codes of money sent through Western Union, Post Office or MoneyGram. Once the fraudster has this code, he can withdraw the money from anywhere at any branch."
And DS Mitchell has one last snippet of advice for residents.
"Make sure you check your bank statement regularly and report any suspicious activity immediately.
"Ensure your current address is kept up to date with anyone that is going to be sending you financial information.
"So much mail gets delivered to previous addresses that it can, and does, get into the hands of fraudsters."
