CVV Validation: A Quick Overview
CVV (Card Verification Value) is a three or four-digit number found on credit and debit cards. It's used to verify the cardholder's identity during transactions.
Comparison with Other Security Measures
Two-Factor Authentication (2FA): In addition to a password, 2FA requires a second form of verification, such as a code sent to a mobile device.
Tokenization: This process replaces sensitive card details with a unique token, reducing the risk of data breaches.
Biometric Authentication: Biometric data, like fingerprints or facial recognition, provides a secure way to verify identity.
While CVV validation is a simple and common method, it may not be as secure as these other measures, especially when combined.
