Jackie,
A major problem with T=0 is the handling of Class 4 APDUs: these have
data transmitted in both directions, but TPDUs (as used in T=0) can only
handle data in one direction. Some card readers and their drivers handle
the 'double TPDU per Class 4 APDU' sequencing, others leave it to the
application - this makes offering a universal application impossible.
