 The technology was introduced primarily as an anti-fraud measure, so that a virtual unique credit card number may be generated to settle a specific transaction, on an exact date by an authorized individual.The possibility of a fraud occurring is significantly less than a traditional physical card, which can be lost, stolen or indeed cloned.The number is generated through the use of either a Web application or a specialized client program, interacting with the card issuer's computer, and is linked to the actual credit card number.
