Virtual PIN

Quick Reference

An unusual method of carrying out financial transactions over the Internet. It was devised by the company Virtual Holdings. A customer is given a virtual PIN which identifies them. The buying cycle for purchasing is as follows: the purchaser sends an order to a vendor together with his or her virtual PIN; the vendor transmits this PIN to an authorization company; the authorization company then contacts the customer asking if the vendor's charge is known to the customer; if the customer replies with the word YES then the transaction is allowed but if the reply is FRAUD then the transaction is illegal. This form of security relies on the huge difficulty in intercepting a number of different but related email messages.
