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: I want a tool to get bytecode speed time

What exactly do you mean by bytecode speed time? I'm unsure what that means.

Re: how the card reacts to faulty ISO7816 APDUs

You are going to want to read the 7816-4 standard. It has all of the command/response and error information in it.
ermmm... ah!. ISO/IEC 7816-4:2013 is the standard number and it's the latest revision.

Re: How to create a method to store transactions logs in java card

If you only need to keep a certain number, use a circular file. When it fills it starts overwriting the oldest. If you have to keep them all then a record based file. It also depends on if they are the same length or varying lengths.

Re: Find a kind of card with PKCS11 module

I think it's not so much the card as the softwate drivers. Google for 'OpenSC' on Github or Sourceforge and they have software to setup PKCS11.

Re: Any implemention of javacard3 in real life

If you request when purchasing, they can set at least the A40 and A22 (maybe others, not sure) to use JC3.0.4... and I think the SDK's from Oracle have example applets showing use of those features. The SDK's are free download on the Oracle website.

Re: What is the best solution to store dynamic data on smart card?

You might want to look at the photo applet demo that comes with the Javacard sdk from oracle and also the openpgp applet here in the forums. They should give you some ideas on how to do what your looking for.

Re: When and how to use Key Diversification data?

Diversified keys are basically an encryption of a base key with other data, such as the 2 you mentioned and usually some random bytes as well. Usually used as short term keys like session keys for SSL/TLS or data between card and PC for mutual authentication without exposing the base key to being pi...
