3D Secure fraud detection

The conventional name 3D Secure stands for security protocols Verified by Visa (VbV) for Visa Circuit and Mastercard Identity Check for Mastercard Circuit. The system requests the authentication of payment by the Customer: during every purchase made on your e-commerce website, the Customer could be asked to insert a dynamic security code – that will be received through SMS – to complete the operation. Once the authentication phase is completed, the transaction follows its normal authorizative way.

Thanks to liability shift, infact, in case your Client does not recognize a purchase, the responsibility of the transaction would be on the Issuing Company. Liability shift is applied according to Visa and Mastercard rules detailed in the document Verified by Visa and Mastercard Identity Check – instructions and rules.

The CV2 security code

Security Code CV2 (CVV2 per Visa, CVC2 per Mastercard) is composed by the last three digits present on the back of the credit card. Asking for CV” in phase of authorization it’s important to verify the buyer is really in possess of the credit card and guarantees a sensible reduction of frauds on your load.

In order to secure your remote selling, besides explaining to your customers what a security code CV2 is, you must require CV2 for all payments, send it together with every authorization request and make it visible only to your staff and to the authorization request.

Finally, you have to adeguate your procedures (forms, organization processes) in order not to preserve CV after authorization, to avoid being subject to penalties expected by International Circuits about the not correct storage of CV2 (the code infact must be destroyed after the authorization request).

Remember that it’s mandatory to require CV2 for both e-commerce selling and mail orders- telephone orders.
