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.
