The plug-in checks customer credit card data, namely, whether the phone number entered by a customer as cardholder phone is in black list or not.
To configure the plug-in:
- Open System > Settings > Fraud Screening.
- Select the Black List of Phones plug-in by clicking the respective link in the Plugin Name column.
- Click Add New Phone. The adding new phone number dialog window is displayed. Fill out the form:
- Type the country code, regional code, and phone number itself into the corresponding Phone Number fields.
- Select the Enabled option to enable the phone number. Before the phone number is enabled it is presented in the black phone numbers list, but remains unavailable for using in fraud screening rules.
- Click Save to finish adding the phone number.
Note: Under specific configuration of fraud screening, the following problem may arise: when a payment is refunded, all its parameters are put into the black lists that are configured (e.g. the customer credit card, black list of service plans, etc). To handle the situation, after refunding, the staff member must adjust the black lists if required (for example, if the credit card is not supposed to be included to the list, staff member must delete it from the list manually after refunding the payment).
