Your website has said that JC10M24R card's NVM: 23KB RAM: 3KB.
But when I used JCAlgTest to test the card, the memory size showed in the result is smaller than what you said.
Where does the difference come from?
JCSystem.getVersion()[Major.Minor];3.0;
JCSystem.isObjectDeletionSupported;yes;
JCSystem.MEMORY_TYPE_PERSISTENT;6384B;
JCSystem.MEMORY_TYPE_TRANSIENT_RESET;2471B;
JCSystem.MEMORY_TYPE_TRANSIENT_DESELECT;512B;
JCSystem.MEMORY_TYPE_TRANSIENT_DESELECT;512B;

AlgTest.cap has occupied some memory.

The memory value showed in the result is the remaining memory after you uploaded algtest cap file. You can code an simple applet by yourself to get the exact memory size.

But a simple applet will also claim some memory. Not so much as a big one but some bytes
So if the card does not support a propriatary command to get the size you will never know it

Get Card MemInfo Applet takes up to 2K bytes NVM space and does not require COR / COD space. So the result is almost the actual card space info.

We can provide the command to get JC10M24R card memory information.
