(Thx. To hariharan swaminathan, MUSCLE archjives, august 2, 2001)

My impression is that T=0 is becoming the default _required_ protocol of
the newer card-generations (in Europe), but that T=1 has the advantage
of being considerably faster. This impression stems from a few recent
RFP's for RSA SC's. 
Be aware that some (proprietary) drivers for SC/SC-readers have only T=0
to support certain cards natively (although in hardware, SC and reader
support also T=1). 

Something which is odd because of the growing memory on SC's (and the
groing requirement of having storage for certificates, multiple
applications on-board etc.), and thus reading time becomes longer (for
example to know the P11/P15 contents of a certain card when inserting) ?

T=0 is character-oriented protocol
T=1 is block-oriented.

find ISO7816-3

in practical terms, you have to see what protocol does the underlying 
architecture adheres to. For example, in Singapore, most of the cards 
are T=0 and in japan most of the cards and terminals are T=1.

And up to today, the general agreed norm would be for the terminal to 
accept T=0, T=1 + T=?? cards depending on applications and for the card 
to talk their specific T=0 or T=1. There are methods for describing this

T=0, T=1 protocol type selection in the ISO docsuments.

on a technical note, they are just two standard methods of handling data

transfer.
