Re: decrypt viaccess tv
I can not understand your question well. Do you mean you want to know the card type ? And why do you want to extract the file to copy on cards ?

Re: Got 64 00 when I installed the package
Could you tell us more about your question?
e.g. some basic information of your card and your package
The most quickly method is to ask your card provider!

Re: how the card reacts to faulty ISO7816 APDUs
Also remind that there may be specifications of how to handle different errors depending on what exactly you are working!

Re: how the card reacts to faulty ISO7816 APDUs
You can refer to ISO7816 specification for more error code usage.
You can also specify your own error codes which are not specified in the standard.

As @ThePhoenyx said, AES is used in SCP03.
So it's impossible to use AES in SCP02.

Re: How to handle java card transaction when power loss or removing the card from smartcard reader
Within transactions writes to persistent memory such as EEPROM or flash are handled atomically. That is: as if all the writes to persistent memory are part of one big action. To create an atomic copy you need to use Util.arrayCopy(). There may also be other actions that can take part of atomicity. I...

How does JCOP card support SCP01/02/03 simultaneously?
I saw a datasheet of JCOP card - J3D081. Datasheet Link: http://www.motechno.com/uploads/media/J ... P2.4.2.pdf
And It shows that this card supports SCP01/02/03 at the same time.
How does the card implement this ?
