What is the primary aim of customer authentication in payment systems?

The primary aim of customer authentication in payment systems is to prevent unauthorized transactions. Ensuring that only authorized individuals can complete a transaction is crucial for maintaining the integrity and security of payment systems. By verifying the identity of the customer through various methods, such as passwords, biometric data, or two-factor authentication, payment systems can effectively guard against fraud and cyber threats. This protective measure not only enhances customer trust but also safeguards sensitive financial data from being accessed by malicious actors.

While options like confirming credit scores, streamlining payment processes, and encouraging frequent buying have their own importance in the broader context of financial transactions, they do not directly relate to the fundamental role of customer authentication, which is primarily focused on securing transactions and preventing unauthorized access.
