5) Be Vigilant with Refunds and Chargebacks: Be careful when issuing refunds or processing chargebacks, as these can be signs of fraud.

6) Stay Up-to-Date with Security Measures: Stay informed about the latest fraud trends and security measures, and regularly update your website and systems to ensure that they are secure.
