If you are already familiar with 3DS, check our integration methods:
3DS (Three-Domain Secure) is a security protocol that adds an extra layer of verification during online payments. It works by securely communicating with the cardholder’s issuing bank to confirm their identity before authorizing the transaction. This significantly reduces the risk of unauthorized card usage and fraud.
The diagram below describes the protocol flow:
Below, an example of the authentication process:
John purchases a cellphone from an e-commerce shop using his personal computer.
The cellphone shop, integrated with PayU's authentication service, wants to verify that John is making the purchase. They send the transaction for authentication.
Through 3DS communication, the issuer receives the authentication request and begins reviewing the shared data.
The issuer successfully authenticates John. As the risk was low, the authentication was silent without contacting him.
For higher-risk transactions, John may receive a simple challenge, such as an OTP sent to his phone.
John receives the confirmation of his purchase and later on, he receives the cellphone at home.
Increased security and reduced fraud: By verifying cardholder identity, 3DS helps prevent fraudulent transactions. Additionally, in case of a fraudulent chargeback, the liability often shifts to the issuing bank.
Improved user experience: Modern 3DS implementations ensure a smooth authentication process with minimal disruption to the user’s shopping experience.
Regulatory compliance: 3DS adheres to EMVCo standards and regulations in many markets, ensuring compliance for merchants and payment processors.
