Mobile phone charge card notification and authorization method
An added level of security is provided for charge card transactions. Upon presenting a charge card number for a purchase, for example, the cardholder receives a message on his cell phone or PDA that a charge authorization request has been received. The cardholder may also be prompted to reply with a password or a PIN, so as to add a second security authorization.
