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

To enable RRP support, we need to modify tag DF811B , B1b5.


the following tags should be added 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’


check  TVR (byte 5) to see if RRP was performed  and result.
