Extended Length APDU
Hi all,
simple question here:
Is anybody aware of a commercially available (or soon) Java Card implementation that supports extended length APDUs? I really don't care whether its through JC2.2.2 or some proprietary mechanism.
If you know of something, please let me know. Thanks!

I did not see any Java Card smart card which supports extended APDU. I think the problem is the global APDU buffer size on-card. Theoretically, if the card supports extended APDU, it must be able to store up to 65kB in the APDU buffer, which should be by definition transient. There could be a solution with some smart design on-card or proprietary middleware for the reader ...
Someone mentioned here a company (Athena Smart Card Solutions, Japan) which supports Java Card 2.2.2 . I checked on their web-site and they claim to have extended APDU support as well:
T=1 Protocol T=1 with PPS for speed enhancement with extended APDU length support ...
