For Visa, Amex, and Discover: tag 9F66
For Mastercard Paypass/ MChip: Tag FFFC
For supporting MSD only for Visa, Amex, and Discover:
You have to set Tag 9F66 to 80 00 40 00 in your default config group (group 0)
For Master card paypass, you have to set tag FF FC to 01 in your paypass group (group 1)
The easiest way to set this is through the uDemo:
For setting Visa:
Save terminal data command saves the default TLV values in group 0
For setting Master card:
After applying these settings, your contactless terminal should only read MSD cards.
You can confirm this by preforming a contactless transaction and looking at Tag 9f39( POS entry mode).
9f39: 91 means contactless MSD transaction
9F39: 07 means contactless EMV transaction
If you try to read a contactless EMV card with these settings, the transaction should terminate and you should get an ICC response of 69 85 (command Not allowed)
