Currently, for additional authentication of the customer, the most issuing banks operate according to the 3-D Secure 1.0 protocol version 1 for all types of cards.
For a more secure authentication process, issuing banks and payment systems are switching to a new version 2 of protocol 2.0 for all types of cards (VISA, Mastercard). To support a new generation protocol, a merchant has to make changes to the customer authentication process.
To start the order payment, the merchant sends an authorization request to the IPS Assist server. The following data about the customer device and browser must be added to the usual request parameters, if this has not been done before for operating with the SOFI. This data is required in the new 3-D Secure protocol version 2.0 protocol.
