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: How to read and write biometric data from/to a java card

An APDU (Application Protocol Data Unit) is actually the transport protocol (like tcp/ip) between the card and the computer. If you need to do unusual things you would need to learn this, similar to needing to learn tcp/ip to talk low-level to a router. When you create an applet you need to set an A...

Re: Does IFD A40cr cards support ECC algorithm?

It can, you just have to request the ECC option be installed when you order it.

Re: Suitable JCOP cards or FEITIAN cards for MUSCLE applet

Personally, I would chose one at least 64k in size. If you're going to use ECC keys and signatures make sure the card has that. JCOP cards, I would go with the J3(A or D)081 cards. For Feitian, the A40 is good, just request that the ECC option be installed.

Re: How to compute the digital signature in this Applet?

You have done a verify but have you created the RSA keys (public/private) for the 3 functions (being sign/encrypt/authenticate)?
What the error is, it's telling you no key is there.

Re: JCOP Tools

I am using JCIDE now. I have also installed Eclipse with some javacard plugins. I use that for full java work as well as Javacard work.

Re: How many logical channels does JCIDE debug support?

Check the APDU api. The CLA byte is different for #4-#19.

Re: How to encode an ECDSA Public Key on java card

If it supports ECDSA, just import it with a setting of exportable. You would then be able to export it later to pass on to another card. As for saving things as objects, I would recommend using the muscle or coolkey applets as they both have 4 files that anything can be saved to. Just put the key in...

Re: Two questions about a simple java card applet

The "& 0xFF" is ANDing the CLA byte with FF. It's normally used as a way to isolate one bit or set of bits to see if it's set or not, such as F1 AND checkbyte == 0 would check for any of bits 1 and 5-8 being set. Why in sample you showed they used FF I'm not sure, I'd have to see more ...

Re: JCOP Tools

After asking around, Jcop is built for Indigo or earlier. No one has got it to work(or just don't want to answer me) and since I found other plugins that do work, I'm setting it aside. And the only way to get a working, up-to-date version is thru NXP. <sigh> :(

Re: How to encode an ECDSA Public Key on java card

If the card you are using doesn't have ECDSA abilities, I would suggest saving it as a byte object or wrapping the key(encrypting it) and then
saving it. It's about the only ways I can think of.
