• CLA = 0x80
  • INS = 0xC1
  • P1 = 0x00
  • P2 = 0x00
  • Data = a sequence of 32-bit integers
  • Response SW = 0x9000 on success, 0x6A80 if data is invalid
  • Preconditions: Secure Channel must be opened, user PIN must be verified

Sets the given sequence of 32-bit integers as a PIN-less path. When the current derived key matches this path, SIGN will work even if no PIN authentication or pairing has been performed. An empty sequence means that no PIN-less path is defined.
