          You should download java card 2.2.1. It is available on oracle website.
          Don't go for classic i.e, 3.0 as no real cards are available for that version.

                  Yes you can use but it is stated in many other threads by Sir Shane that there is no real card available for that version and it is useless to code in that version yet.

                    Yes, you can use Classic Edition in JavaCard 3.0

                    Btw, don't limit yourself to "Card" when talking about JavaCard, it's a specification that you can find on other devices rather than smartcard. In terms of JavaCard 3.0, there's a partial implementation of this specification (Connected Edition) physically. As far as I know, There's no fully implementation of JavaCard 3.0 at the moment.

                    For illustration, you can easily find PlaySIM project on google to see how they are playing with "JavaCard 3.0".

                      Hi,

                      For smartcard development stay away from JC 3 all together (for now). There may be some JC 3.0.x classic cards coming soon but if you want to use a card now stick with JC 2.2.x.

                      While there are other types of devices that could be running Java Card, the common use case is still smartcards and NFC devices.

                      PlaySIM has not been modified in about a year and looks to be a dead project. Other than testing, there are better options than a Java Card runtime not on a smartcard. JC was developed to solve a very specific problem of smartcard development. There has been talk of supporting USB flash sticks with a microprocessor running JC3 connected but it seems that secure flash sticks like these have specific encryption etc. While it is possible, there is not a lot out there at the moment doing things like this. Maybe it is an interesting opportunity though... but like I said I think there are more convenient technologies to use for this given microprocessors in these devices are becoming more powerful and have more RAM etc.

                      As always, that is just my $0.02 :)

                      Cheers,
                      Shane
