What does improved security in digital payment systems contribute to?

Improved security in digital payment systems significantly contributes to higher customer satisfaction because it instills confidence in users when making online transactions. When customers know that their financial data is protected against theft and fraud, they are more likely to engage in digital transactions without fear. Enhanced security measures, such as encryption and authentication protocols, reassure customers that their sensitive information is safe, which can lead to a positive experience and greater loyalty to the service.

The other options do not reflect the benefits of improved security. Increased chances of fraud would deter customers, while a loss of customer trust would lead to dissatisfaction rather than enhancement. More complicated payment processes can frustrate customers, further detracting from their overall experience.
