MC 3.1.1 supports RRP. This applies to all NEO 2 projects.

To enable RRP support, modify Tag DF811B, Byte 1 Bit 5.


Add the following tags to MC group:

  • DF8132 02 00 00 ; RRPrMinGrace  
  • DF8133 02 09 60 ; Maxium Relay Resistance Grace Period = RRPrMaxGrace 
  • DF8134 02 0F A0 ; Terminal Expected Transmission Time For Relay Resistance C-APDU 
  • DF8135 02 0F A0 ; RRP Expected RAPDU
  • DF8136 02 0F A0 ; Relay Resistance Accuracy Threshold = RRPrMaxGrace = ‘0FA0’


Next, check TVR (Byte 5) to see if RRP was performed and the result.
