Card content management tool that supports SCP03

I am finding a card content management tool that supports SCP03. I have already tried pyresman, pyapdutool, GlobalPlatformPro.
All these tools don't support SCP03. Does anyone use the similar tool that supports SCP03?

Re: Array larger than 32K bytes

2.2.4.3.3 Arrays Arrays can hold a maximum of 32767 components.


So, 32K Bytes is the limit for an array size.

Re: error occurred when activating JCOP tool

I experienced the same issue before. But I didn't find the solution.
I also tried to contact NXP, but there is no response at all. :(

Re: JavaCard BioAPI

Hi friend!
I also works on this. Hope we can make progress together!

The VERIFY command invokes a vendors algorithm. To invoke your own, you would have to capture the biometrics and store it using your own template. Then you can perform a match using your own algorithm.

I would be appreciated for any...

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 ...
