## What is NDM?

Netcetera Demo Merchant (NDM) is an application that integrates the Netcetera’s 3DS SDK product. The demo application provides an EMV 3DS authentication checkout experience with all required payment details, as a part of EMV 3DS authentication processing for Mastercard Issuing App Channel validation in production. Here, Issuers can register and use Netcetera's Acquiring services to initiate Application-based 3DS transactions, troubleshoot and fine-tune their setup. By doing this, issuers can improve the transaction processing in production environment and to decrease the abandonment rate.

 

The user should use only production Mastercard cards, should enter the card details and initiate different type of transactions. Before initiating the EMV 3DS transactions, the user should register the issuer data on the following site https://3ds.netcetera.com

The NDM application only processes EMV 3DS authentication flow and does not  authorize or clear transactions. The app provides the following options:

 

1. Handling of both frictionless and challenge flows.
2. Support of all challenge types including the OOB flow in which the app can be directly opened from another authentication application (feature available in 3DS 2.2 protocol version).
3. Nonpayment and payment options available
4. Requesting different UI types:
- Native UI
- HTML UI
- Both (ACS preferred)
5. Requesting different EMV 3DS Versions via settings button…
- 2.1.0
- 2.2.0
6.  Errors from the transactions shown in UI screen
