Abstract
The invention relates to a secure wireless authorization system by which a user can employ a wireless device to authorize a request that is initiated by a remote third party and transmitted to the user by an authorization server. The system includes the authorization server that is linked to the third party by way of a communications connection and a wireless device that is adapted to securely store an encryption scheme and create a secure authorization from the user in response to the third party request and has the ability to establish a secure wireless connection over which the secure authorization is transmitted from the user's wireless device to the authorization server. Pre-authorization, real-time authorization and post-authorization methods are disclosed by which user authorized transactions can be completed by way of the authorization system of this invention.
