When the magstripe transactions in the terminal are disabled, contactless magstripe is not getting disabled. How to disable the Contactless MSD as well?

Answer:

Different Brands have different tags to disable the MSD.

For VISA/discover, you want to check tag 9F66 based on the info below and set the Byte 1 bit 6(B1b6) via command 04-00, data 9f660420004000: 

 

For MC, you shall check tag  Df811B in Group 80 for the NEO II product based on the definition below: 

If you wish to disable MSD on the NEO I reader, you shall modify tag FFFC in Group 1 (check NEO I IDG for tag definition and set tag FFFC to 02. for support M/Chip only)



Check in the related IDGs for default group designation details
