You can prevent fraudulent activities at the outset by detecting the patterns, and identifying the people behind the scams. Businesses can check their buyer’s CVV (Card Verification Value), verify the shipping address and other credentials to prevent fraud. Furthermore, fraudsters are more likely to deal in large transactions once they get hold of your personal data. Thus, setting a maximum expenditure limit on the card, and flagging unallowed transactions can help you detect – and prevent – payment fraud.
