Re: What's the difference between APDU and TPDU?
The IFSC is dedicated to T=1. For APDU level, maxCCIDMessageLenth decided fsc length. In fact,we can send any length by only need to take care of this length smaller than maxCCIDmessageLength.

Re: Is there any way to get the EEPROM size of a Java Card?
Note, the return value type of getAvailableMemory() is short. It max value 32767. If getAvailableMemory() returned 32767, you should called this method again to check wether the card has more memory.
