 The VP5300 reader failed the MasterCard test case MCM01Test01Scenario01 with the reason "Step 2 In the MasterCard Simulator, the CVC3 retrieved from Track 2 is not validated".  How to correct this?

Answer:

You need to add the DFEF4E029F61 tab in the MasterCard config group (80).  The transaction will return the 9F61 which is the track 2 CVC3.
