Ecommerce requires diligence in securing customer transactions. Both AVS and CVV systems are critical for preventing fraud.

What is AVS?

The Address Verification System (AVS) checks the billing address provided during an online transaction against the address stored with the credit card issuer. An AVS match provides reassurance that the purchaser is who they claim to be.

What is CVV?

CVV, or Card Verification Value, is a code intended for online purchase security. When a consumer enters their CVV during a transaction, it serves to verify that they have physical possession of the card.

AVS and CVV Mechanism

When processing a transaction, both AVS and CVV are checked for validity. By ensuring that the entered information matches the issuer’s records, the risk of fraudulent transactions is significantly reduced.

Understanding Authorization Responses

Payment processors utilize various responses to indicate transaction outcomes:

• Approved: The transaction is successful.
• Declined: The transaction did not pass checks and has been rejected.
• Refer: More information is needed prior to approval.

Best Practices for Ecommerce

To best implement AVS and CVV technologies, consider the following practices:

• Regularly review and update security settings.
• Use fraud detection services alongside AVS and CVV measures.
• Educate customers on secure payment practices.
