Payment Fraud Prevention

By using this module, you can easily fetch the complete data associated with a debit/credit card, including its `type` (debit or credit), `schema` (Visa, Mastercard, etc.), `brand` (gold, platinum, etc.), `bank` details, and more. This information can be used for a variety of purposes, such as verifying a customer's payment details, detecting fraudulent transactions, and providing personalised services to your users. 

BIN/IIN Lookup

This method allows you to validate International Bank Account Numbers (IBANs) and retrieve additional information about the country associated with the IBAN

IBAN Validation

This method provides an additional layer of validation for your system. While validating email syntax is important, it is not sufficient. This method goes beyond syntax validation by checking the domain's validity, the availability of the Mail Service, detecting Disposable Email (Temporary Emails), etc. By utilising this method, you can ensure a more thorough validation process for email addresses.

Email Validation

This method can be used as an extra-layer of your system for validating phone numbers. It validates phone number syntax and valid-possibility.

Phone Number Validation

This method can be used to detect abuse of your website/app. It's a great way to know more about your user inputs and whether they contain profanity (bad words) or not before releasing them to the public.
