Mastercard has announced the integration of generative artificial intelligence into its fraud detection systems, significantly enhancing its ability to identify compromised credit and debit cards before they are used by criminals. The new AI technology is expected to double the speed of fraud detection, allowing banks to replace compromised cards more quickly and prevent unauthorized transactions. The company aims to spot patterns in stolen card use faster, thereby mitigating the risk of cybercriminal activity. Mastercard made this announcement on Wednesday, highlighting its capability to stop cybercriminals from abusing compromised account numbers.
