Contactless virtual reader

Hi folks, I have noticed that with the new JCIDE version, there is still a Contact and Contactless virtual reader but I'm having great difficulty working out how to get the contactless reader to work.

Re: JCKit JAVACOS_7.1.0.0 released

Hi thanks for the update! When I download it from the main Javacos forum web site, the zip file says v7.1.0.0, but the installer inside is v6.1.0.8!
I was able to get the correct one from Google Drive however.

Bug: Javacard 3.0.4 SDK mismatch

Hi folks, I recently attempted to switch a project from JC2.2.2 to JC3.0.4. Recompiling worked fine until I tried to add some features that weren't available until 3.0.4, specifically, to use the Applet.reselectingApplet() method. The compiler failed saying that the method didn't exist. I checked th...

Re: Announce the release of JCKit JAVACOS_Beta_2.0.2.8

So, if T=0/T=1 is selected, then T=1 does not work. But if T=1 only is selected, then it works.

Thanks,
