x9.59 standard for all elecronic payments can use digital signatures w/o 
PKI or certificates ... just public key registered with account and 
connectivity to senders financial institution. It isn't "centralized" any 
more than the existing payment card operation is centralized .... aka huge 
number of different consumer financial institutions all with their 
individual operation and account records. however, much of it is based on a 
private network interconnecting all of these financial operations that 
predates the existing internet ... but effectively functionally equivalent.

The existing payment card infrastructures are open in the sense thay they 
do have an international standard, iso8583 .... in much the same way that 
certificates have iso international standard. and there are numerous 
interconnects between the internet and these infrastructure ... witness the 
existing electronic commerce. It is less open than the "internet" in the 
sense that there are contractual, institutional, and financial obligations 
that are necessary to directly participate (but i believe that will tend to 
be always true except in the cases of toy demos). However, that isn't 
precluding the migration of more electronic commerce related traffic to 
internet-based technology in various ways. The issue isn't directly whether 
it is internet-related technology or non-internet related technology .... 
but much more of an issue whether there are explicit legal and other 
obligations required to participate.
