JavaCard OS

I have finished an Applet that only has some basic crypto operations. Now I want to write a client application that uses my Applet. But I have some question. Please help me to be more clearer. Thanks.

Q1 - APDU I/O (com.sun.javacard.apduio): this does support pcsc readers in JC < 2.2.2, right?

Q2- the native java API javax.smartcardio: I've managed to send some APDU ommands but this API very "raw"

Q3 - What about APIs in other languages ? (C, C++ ..)

If you want something which works according to your requirements, I am suggesting to write your own PCSC wrapper using Windows dlls.

OpenCard Framework ( http://www.openscdp.org/ocf/ ) is a nice alternative.

It has the concept of card service, that enables to write card services that wraps your apdus into conventional method calls.

A short list of host machine (PC computer/server) of possibilities to choose from:

• com.sun.javacard.apduio (Java with Sun package which maybe subjected to depreciation)
• javax.smartcardio (Java - the defacto API)
• OCF (Java)
• jnasmartcardio (Java - alternative wrapper to WinSCard/PCSCLite competing with javax.smartcardio - https://github.com/jnasmartcardio/jnasmartcardio)
• LuaGP (Lua - https://github.com/bondhan/LuaGP)
• PCSCLite (C/C++ - https://pcsclite.alioth.debian.org)
• smartcard gems package for Ruby (Ruby - http://www.rubydoc.info/gems/smartcard/0.5.6)
• pyscard (Python - https://pyscard.sourceforge.io)

What is the script/programming language you need to use for your project and are you looking for cross-platform uniformity ?
