How Visa employed artificial intelligence to check $40 billion in fraud as scammers also take to AI

 

Originally published on cnbc, July 25, 2024.

KEY POINTS

  • Visa is using artificial intelligence and machine learning such as risk scoring to counter fraud, the firm said.
  • “We look at over 500 different attributes around [each] transaction, we score that and we create a score –that’s an AI model that will actually do that. We do about 300 billion transactions a year,” said James Mirfin, global head of risk and identity solutions.
  • Fraudsters are using generative AI to make their scams more convincing than ever, leading to unprecedented losses for consumers, according to a Visa report.
  • Payments giant Visa is using artificial intelligence and machine learning to counter fraud, James Mirfin, global head of risk and identity solutions at Visa, told CNBC.

    The company prevented $40 billion in fraudulent activity from October 2022 to September 2023, nearly double from a year ago.

    Fraudulent tactics that scammers employ include using AI to generate primary account numbers and test them consistently, said Mirfin of Visa. The PAN is a card identifier, usually 16 digits but can be up to 19 digits in some instances, found on payments cards.

    Using AI bots, criminals repeatedly attempt to submit online transactions through a combination of primary account numbers, card verification values (CVV) and expiration dates – until they get an approval response.
