In my post I am looking at this from an economics point of view. Simply
put: If there is unlimited liability to the credit card holder because
Mallet is stealing card numbers from the telco switch, encyrpted, plain text,
it doesn't matter, there will no users. If there are no users then
there will be no transaction fees generated, no transaction fees, then it
won't be deployed. Therefore, there is no reason to develop the code
or even read the latest and greatest specs. and we are all wasting out
We must recognize that no matter what code we write, how secure it is,
it won't be used until the banks that must clear the transactions
agree to accept the risks of loss in return for their transactions fees.
I haven't seen this from any of this consortiums and would like besides
publishing their specs for the best system agree that this risk bearing
is a necessary step for electronic commerce to become a reality.
I would like to see members of the MasterCard and Visa coalitions comment
on this aspect of the systems that are promulgating. The one who cracks
this nut first without losing their shirt to Mallet will be the winner. The
others that expect us to deploy systems based upon if Mallet breaks the
system, the cardholder and or merchant pays is wasting our time.
MasterCard/Visa, you're going to have to *earn* those transaction fees in

For anybody else that wants to argue about what is more dangerous,
restaurant dumpsters or telco switches, take it to alt.who.the.hell.cares.
