Java Card Host Application (Off-card Application)

To write a java card host application we need JCK 1.6+ as these releases contains the SmartcardIo API. This API have all the necessary functions which we will need to communicate with a real java smart card.

One drawback of  smartCardIo is that it can only communicate with a real smart card and not with a simulator

Below is a simple java card host application. When this application will be executed it will output the world 'Hello World' which we stored in our applet Hello World Applet
