I'm working with jcop version2 card (engineering sample). My applet (cashcard applet) is good working transaction at first..(until about 30th times) for example it is debit, credit, cancel, refund, etc... But, when i do it over 30th times(not fixed), card return SW 0x6F00. what's wrong? so i do that command with problem in applet is changed like following.. => start private void Credit(APDU apdu) { byte[] buffer = apdu.getBuffer(); /* : : */ } <= end but, problem is continuous.. I think it is related with memory variable(eeprom or ram).. or card memory size. because my applet size is 12kbytes. please    More>>

I'm working with jcop version2 card (engineering sample).
My applet (cashcard applet) is good working transaction at first..(until about 30th times)
for example it is debit, credit, cancel, refund, etc...

But, when i do it over 30th times(not fixed), card return SW 0x6F00. what's wrong?
so i do that command with problem in applet is changed like following..

=> start
private void Credit(APDU apdu) {
byte[] buffer = apdu.getBuffer();
/*

*/
}

<= end

but, problem is continuous..
I think it is related with memory variable(eeprom or ram)..
or card memory size. because my applet size is 12kbytes.
