write an application program which can access java card

[Tinatco]

I want to write an application program which can access java card(e.g. read data from card) from my computer. But I am not sure if I must use JAVA language to implement this. Please forgive me if my question is stupid.

You can write the applet in Java, Python and so on. The program language just depends on your own situation.

Hi, I wrote a simple C# app. You can modify for use!

Essentially, JavaCards and other ISO7816 and ISO14443 compliant smart cards will only see APDUs. Any language that can talk to a PC/SC library will give you access to the APDU and that is the thing you need.

It depends a) on your known coding experience and b) the use case.
a) do you have coding experience?
If yes: use the already known language but if not: use java and you can use the same language for on- and off-card code.

b) use case
If it is a programm that should be used in the backend: choose the language you want. If it goes to the customer: use the OS-depending GUI-clicky-bunti coding software
