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.

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.

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.
