A METHOD OF CONDUCTING FINANCIAL TRANSACTIONS

摘要

The invention provides a method of authenticating a user in a method of conducting real time transactions, said authentication method including requesting authentication by a user transmitting a USSD code from a handset to a server, transmitting one or more questions to the handset of the requester, transmitting answers provided by the user through the handset to an authentication server over a mobile communications network, weighting the questions, evaluating the answers, and determining whether the weighted score of the answers is above a minimum passmark before the authentication server authenticates the user for the transaction or rejects the request for authentication. The invention extends to a method of conducting on-line real time transactions using the above authentication method and to a payment system.
