While the cost of scams is rising so is fraud prevention improving, says UK Finance. It says in the first half the finance sector believes it prevented £705.7 million of unauthorised fraud, equivalent to £2 in every £3 of attempted unauthorised fraud.

Purchase scams were the most prevalent authorised push payment (APP) scam in the first half of 2018, accounting for almost two thirds of reported APP cases.

In these scams the victim pays in advance for a product or service, such as a car, electronics or a holiday rental, which is never received or does not exist. It often takes place online, through auction websites or social media.

Katy Worobec, managing director of economic crime at UK Finance, said: “Fraud and scams pose a major threat to our country. The criminals behind it target their victims indiscriminately and the proceeds go on to fund terrorism, people smuggling and drug trafficking, whether or not the individual is refunded."

“The finance industry is committed to fighting back, investing millions in security systems and cyber defences to protect customers.”

UK Finance points out that while the number of payment scams has grown the number was small against a backdrop of over 4.2 billion bank transfers made in 2017.
