Authentication Method

Please specifly the languages you wish to display to your cardholders in the VCAS screens.

Risk Based Authentication

VCAS offers multiple authentication solutions.
The Pass/Fail solution leverages the VCAS Rules functionality to pass and fail authentication based on parameters created and maintained by the VCAS client. No system integration is required for this solution. (If selecting this option, please skip the Step-Up Method section.)
The Pass/Fail/Step-Up solution incorporates the rules from the Pass/Fail solution and also includes a step-up flow to obtain an authentication directly from the cardholder. This solution requires a system integration, please see the System Integration section further below.

Step-Up Method

In this section you will define your step-up method for your 3DS transactions. The step-up allows you to give your cardholders the chance to authenticate themselves instead of failing the transaction. The System Integration section below will be required to support any step-up option.
For windows: Hold down the control (ctrl) button to select multiple options. For Mac: Hold down the command button to select multiple options.
This method is specific to PSD2 SCA compliance. OTP+KBA will leverage the selections in the OTP section above.
Note: This method of authentication is only applicable to API based integrations (Real-Time Data Exchange (RDX)) as the VCAS client will need to perform validation of the Answer in real-time during the transaction. The RDX integration is required to pass the Question & Answer for KBA as VCAS will neither store nor validate the Question or Answer.
For Windows: Hold down the control (ctrl) button to select multiple options. For Mac: Hold down the command button to select multiple options.

System Integration

A system integration is necessary if our systems need to share information in order to successfully perform a step-up authentication.
File Processor (FP) - allows you to drop off cardholder information in a specific file format via SFTP (Secure File Transfer Protocol). This data will be used to facilitate authentication with your cardholders.
Real Time Data Exchange (RDX) - is a web service with 4 conditional API calls used to integrate with Cardinal's VCAS system to facilitate communication and share information real-time between our systems. RDX is flexible and allows you to, based on the authentication solution, determine how involved you would like to be in the transaction flow.

Data Sharing (Optional)

Additional information may be shared outside of the VCAS Portal. The Authentication Data Exchange (ADX) contains the results of the authentication and is sent in real-time API prior to VCAS sending those results back to the merchant.
Data may also be shared via an SFTP file delivery method via the confirmed marking file and the reports shown further below.

Bulk Confirmed Marking (Upload)

File upload by Client to mark transactions as good or fraud via SFTP file.

SFTP Reports (Download)

Additional data available via SFTP file delivery.
For Windows: Hold down the control (ctrl) button to select multiple options. For Mac: Hold down the command button to select multiple options.
