protocol, business (IOTP, Formerly "Open Trading Protocol",

OTP) A specification that provides an interoperable framework

for Internet commerce. It is optimised for the case where the

buyer and the merchant do not have a prior acquaintance and is

payment system independent. It will be able to encapsulate

and support payment systems such as SET, Mondex,

CyberCash's CyberCoin, DigiCash's e-cash, GeldKarte, etc.

IOTP is able to handle cases where such merchant roles as the

shopping site, the payment handler, the deliverer of goods or

services, and the provider of customer support are performed

by different Internet sites.
