Re: What would happen if update a javacard applet
I have not met the needs of applet upgrade, We can only remove the old version, install the new version, then the applet data is lost. We can create a file system cap, all data can be stored in this file system, applet is responsible for processing logic. applet can be upgrade only. But if you want ...

Re: Cannot import visa.openplatform package in JCIDE
I found the JCIDE provider gp211.jar and globalplatform.exp, you can use GP211 instead.

Re: Cannot import visa.openplatform package in JCIDE
I have a test, the visa.openplatfom package need you add external jar.
The path of visa.openplatform jar file is: <JavaCardKit_install_path>\SDK\Tools\JCIDE\apis\op201\op201-src.jar
But the exp file is missing when convert operation.
Maybe JCIDE not support visa.openplatform develop.

Re: How to know supported encryption/sign algorithms in a Javacard
So simple, ask your card provider. If you did not know the card provider, you can only test yourself.

Re: Implement div algorithm in javacard
Why did you write this code? To study? Without the chip-level implementation, the calculation speed will be very slow.

Re: what is the "Feitian R502 SAM1 Reader 0"?
Used to communicate with SAM module. There is a SAM card slot in the R502 reader. You use it when you develop SAM.

Re: How to know the rest amount of memory in javacard
1 Ask the card provider; 2 Write an applet, use the api: JCSystem.getAvailableMemory(), this function can used to get size of RAM(COR or COD) and NVM; You can use the function as said in Javacard API specification; Notice: You can get an accurate value if there is only your applet in the card, and y...
