What you require

In order to use ACI ReD, it is necessary that you observe a few important points.

For the use of ACI-ReD the transfer of additional data is not necessary per payment, hence the additional function/control is carried out directly at the Paygate. Customers are evaluated by ACI-ReD before they are forwarded to the 3D-Secure-Authentication.

The following three scenarios can apply after the evaluation.

Action Control

• Accept
  • 3D-Secure-Authentication is not necessary
    • The payment is forwarded to the acquirer for further processing
• Challenge (offers the following additional procedures)
  
  • The customer is forward to the 3D-Secure-Authentication page to enter the password
    • The payment is forwarded to the acquirer for further processing
  • The customer is forward to the 3D-Secure-Authentication page but DOES NOT NEED to enter the password.
    • The payment is forwarded to the acquirer for further processing
  • The customer is declined
    • The payment is not forwarded to the acquirer
• Deny
  • The customer is declined by ACI-ReD
    • The payment is not forwarded to the acquirer
