By tracking and analyzing verification success rates, you can identify any anomalies or suspicious activities, allowing you to take immediate action and strengthen your fraud prevention measures.
By leveraging SMS verification, you demonstrate to your customers that you prioritize their security and are committed to providing a safe online shopping experience. This helps build trust, enhances your brand reputation, and encourages customer loyalty.

By understanding its workings and potential pitfalls, you can leverage this tool to enhance the security of your online store and offer your customers a safe, secure shopping experience.
