javacard-rpc-client-kotlin

Thin Kotlin/JVM runtime for javacard-rpc generated clients.

It mirrors the role of javacard-rpc-client-swift on the Swift side:

  • APDUCommand and APDUResponse
  • APDUTransport
  • TCPTransport for the local jCardSim bridge
  • DataPacker helpers for APDU payload assembly

This package is intended for development and integration testing. Production transports can implement APDUTransport over BLE, NFC, or any other channel.
