Mobile payment systems enhance transaction security through various mechanisms like encryption, biometric authentication, and tokenization. Encryption protects sensitive data during transmission, while biometric features such as fingerprints or facial recognition provide an additional layer of verification. Tokenization replaces actual card information with a unique token, minimizing the risk of data breaches. Furthermore, many mobile payment platforms implement fraud detection algorithms that monitor transactions for suspicious activity. These combined security measures ensure that users can conduct financial transactions safely and confidently.
