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) ?

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. jipi *************************************************************** Unix Smart Card Developers - M.U.S.C.L.E.
