Hello TapLinx team,
Thanks for your help. Your response time was excellent!
I'm theorizing that I am not properly allowing layer 4 communication. I've been able to write the AES keys at 0x9000, 0x9001, and 0x9003. However, I've only been able to authenticate with the SL1 Card Authentication Key at 0x9004. It looks like this is available in ISO14443-3 mode while the SL3 Switch Key requires ISO14443-4 mode, just as you suggested. This makes me think that I'm not properly enabling ISO14443-4 communication. Does that sound correct?
Thanks for your help,
-Kevin
