Understanding the 3DS Authentication Flow

3DS authentication happens in a series of fast, behind the scenes steps that validate identity and keep checkout moving.

Data Collection

SeamlessPay collects device, behavioral, and transaction attributes in real time. These signals help issuers recognize trusted customers early.

3DS Routing

The transaction is sent to SeamlessPay’s 3DS Server, where authentication logic classifies the risk profile and prepares the request for the issuer.

Issuer Review

The issuing bank evaluates more than 150 shared data points to determine whether the transaction appears legitimate or requires additional verification.

Frictionless or Challenge

If the issuer trusts the transaction, authentication completes silently. If risk indicators appear, the issuer requests a challenge such as biometrics or an app confirmation.

Possible outcomes:

Frictionless → Authorization

Challenge → Verified → Authorization

Authorization

Once identity is verified, the transaction moves to authorization with a higher likelihood of approval and stronger fraud protection.

FAQ

What is 3D Secure?

EMV 3D Secure is a global authentication standard that verifies customer identity during online card payments.

Will 3D Secure reduce chargebacks?

Yes, 3DS significantly reduces fraud-related chargebacks. With 3DS Liability Shift, the financial responsibility for fraud-related chargebacks shifts from the merchant to the card issuer.

Does 3DS provide liability shift for recurring transactions?

Only customer-initiated transactions can be 3DS-authenticated for liability shift. As a result of the original 3DS authentication, subsequent merchant-initiated transactions (e.g. subscription payments) have significantly reduced fraud risk, but do not have liability shift.

Do I need 3DS if I sell in the U.S.?

3DS is not mandatory, but it boosts approvals and reduces fraud significantly.

Does 3DS support biometrics?

Yes—Face ID, Touch ID, and app-based confirmations are fully supported.

Can 3DS help with PSD2 compliance?

Yes—SeamlessPay provides full SCA coverage and exemption logic.
