The Issuer Simulator will validate MChip4 cryptograms (SKD=2.1 or CCD or UKIS) and CVC3s with IV generated in the standard way, including PIN IVs. The simulator will also validate online PIN blocks that are part of the authorisation request. The simulator can provide ARPC with response code and also scripts as part of the authorisation response.
The Simulator not intended to replace the MasterCard Authorisation or Financial Debit Simulator (MAS and MDFS – both paid for fully featured products) and cannot be used instead of these products for formal validation processes such as NIV, but only to allow simple end to end demonstrations of transactions performed with a MasterCard Terminal Simulator and for checking of test card ARQCs and CVC3s and if required returning scripts. It only simulates Issuer processing of authorisation requests. For further details on MAS or MDFS, MasterCard Customers should consult MasterCard Online.
