Abstract: The invention consists of a method and system for secure mobile ticketing through the use of a mobile device with display output and data input capabilities. The system utilizes a cryptographic security string appended to a URL and embedded in a 2D barcode to securely create an electronic ticket which is displayed on the mobile device display for redemption, redeem the displayed electronic ticket by means of optical scanning, and optionally register and authenticate a ticket scanning unit. The system utilizes real-time internet communication with a remote server for ticket distribution, redemption and ticket scanning unit registration and authentication to restrict unauthorized creation or redemption of electronic tickets and to reduce queuing.

Abstract: A system and method for a mobile device to initiate and enable contactless transactions and services between a user of said device and remote servers controlled by a service administrator. Such device will have an application or other facility residing it for reading data embedded in an object. The present invention provides for the loading of one or more service profiles to such mobile device based on certain unique identifiers of the user, such as a PIN or username and password, along with the unique ID of the mobile device itself or an administrator-assigned ID. Such service profiles are stored on such mobile device with a unique service ID and a unique service URL for such mobile device to transmit and receive data, along with certain unique identifiers, in real-time and in a secure, closed-loop environment.
