There is no oficial spec 3D-Documents, as far as I know. Nevertheles, VISA
and Master card have several powerpoint presentations explaining how
liability can be in the acquiring side, in the issuer side and in the
clearing network.
Important documents are those explaining how since introcuction of 3D-SET
concepts ( not very technical themselves) in october 2000, chargeback rules
start changing. From June 2001 if the cardholder buys in a shop using SSL,
BUT the shop has also the ability to allow payments through SET, THEN the
transaction canot be charged back and liability remains in the issuer side.
Issuer can choose several way to allow for SET payments (from standard SET
wallet to server based SET wallet), so its cardholder at the end will be
using one or another flavour of SET.
By the way, server based SET has an important advantage: the wallet weights
between 50 k and 100k, agains 4M-6M in standard SET.
But in fact that is not such a big advantage compared with the 500 k size of
the easy-SET wallet, that includes a full SET implementation inside, without
the need of a server support.
(Server wallet rational is that you don�t need all the software in the
wallet, just software enough to transfer information to a server, let the
server manage crypto and additional issues and transfer info again to the
thin wallet so it behaves as a ful wallet regarding merchant. But that seems
to imply that previously nobody was able to make wallets under 1M size).
