What is 3DS?
3DS (Three-Domain Secure) is a messaging protocol that enables the issuers to authenticate their cardholders during the online shops. This authentication is performed before the transaction is authorized and follows the next flow.
The next infographic explains the authentication flow for 3DS.
John buys a cellphone through an e-commerce shop in his personal computer.
The cellphone shop, which is integrated to the PayU authentication service, wants to verify that John is the one making the purchase, so they send this transaction to authenticate.
Through 3DS communication, the issuer receives the request to authenticate the transaction and begins to review the shared data.
The issuer authenticates the buyer that is making the transaction successfully. Since the risk was low, the authentication was silent without contacting John.
When the transaction involves higher risk, John may receive a simple challenge, such as an OTP sent to his cellphone.
John receives the confirmation of his purchase and later on, he receives the cellphone at home.
