Method and system for delivery of a secure document
Abstract:
A method and system for issuing secure documentation, such as tickets or coupons. The method includes producing a secure document having printed information and coded data thereon, the coded data including a unique identifier indicative of the secure document. A correspondence is recorded, in a computer system, between the secure document and validity status and/or authenticity information relating to the document. A sensing device is provided, adapted to sense the coded data on the secure document. The sensing device is further adapted for communication with said computer system, whereby the validity status and/or authenticity of said document can be determined by sensing said coded data to obtain the secure document unique identifier and communicating with the computer system to determine the validity status and/or authenticity information corresponding thereto. The secure document can be produced on demand in response to a request from a user to an issuer by way of the computer system, wherein the secure document is produced at the user's premises.
