👉 Mastercard's "Infection" feature is an innovative security measure designed to protect cardholders from unauthorized transactions by simulating a compromised card. When a transaction occurs, Mastercard sends a unique code to the cardholder’s device, which mimics the error message typically displayed when a card is lost or stolen and the card is used without authorization. This alerts the cardholder to potential fraud, prompting them to verify the transaction and take action if necessary. If the transaction is confirmed as fraudulent, Mastercard can immediately block further charges, enhancing security and providing peace of mind to users.
