Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

Re: Announce the release of JCKit JAVACOS_Beta_2.0.2.7

Great! This is really an excellent product guys. The best generic Javacard development environment out there by far.

Re: Debug Stop Work

Could you check whether you are communicating to the simulator with T=0 or T=1? I have experienced that T=1 does not work correctly which I have posted about separately here: https://javacardos.com/javacardforum/vi ... e%3A#p4279

Re: Announce the release of JCKit JAVACOS_Beta_2.0.2.7

Hi guys, One bit of feedback on Beta 2.0.2.7 is that the simulators don't seem to work with T=1. Steps to reproduce: - Install JCKit Beta 2.0.2.7 - Create a new project/solution - Select 'Standard', 'Default', 'A40CR', or 'eJava Token' simulator - Select 'T=1' - Enable PC/SC (for testing T=1 connect...

Static analysis and code optimisation

I've been looking at options for Javacard code analysis and although there are many whitepapers available discussing the topic, there seems to be few available tools! I've so far used: - PMD - m - FindBugs - m - Proguard - m PMD and FindBugs both give good output based on the Java language, but fail...

Re: How to install applet to java cards

Do you particularly want to code this or it sufficient to just use a tool? There are plenty (pyApduTool, GPShell, GlobalPlatformPro, etc etc) and if you are looking to implement in code there are a few good libraries out there, depending on which language you want to use.

Re: Announce the release of JCKit JAVACOS_Beta_2.0.2.7

This is probably the number one feature I've been hoping for! Life just got a bit better :)
If there was the ability to alter memory / variables while stepping through, this would be an incredibly powerful combination for rapid development.

Re: Announce the release of JCKit JAVACOS_Beta_2.0.2.7

Thank you, all working now.
Being able to reference the call stack and byte code so easily is great! Thanks very much for maintaining such a useful tool.

Re: Announce the release of JCKit JAVACOS_Beta_2.0.2.7

Hi! I've just done a clean install of beta 2.0.2.7 (removing the old version first) and it gives two options: 'Get Register Code' and 'Verify Register Code'.
When I click the first one it just takes me to the forum home page. What's the procedure for registering this version?
Thanks!

Re: SecureChannel.unwrap fails in JCIDE simulator when no data present

Thanks kuafu for checking this! I'm not sure why but I'm not getting the same results you are. Apologies, my sample APDU's did not include the CLA=04, but I have been testing with this. Here's an APDU script of the whole session with notes I am executing this using the JCIDE simulator (tried both A4...

SecureChannel.unwrap fails in JCIDE simulator when no data present

Hi, I've implemented GP SecureChannel handling in an applet that enforces encryption and mac (CEnc+CMac) on the incoming command data. This is generally working fine but in the JCIDE simulator, the call to unwrap() fails when there is no CDATA in the APDU. I've then tested this on several real cards...
