SECURE PLACEMENT OF CONFIDENTIAL INFORMATION ON A CIRCULATED BLANK TICKET ABSTRACT OF THE DISCLOSURE Secure placement of confidential information on tickets distributed in blank is permitted by opaquely overlaying an area of the ticket upon which the information is to be placed in visible form and employing a printing apparatus that prints the visible information on the ticket area through the opaque overlay without leaving any easily- discernible trace in the overlay that reveals the imprinted information. A ticket can be given in blank to a ticket holder. Then, when the ticket holder makes an exchange in order to receive the information, the information can be placed on the ticket, with the opaque overlay concealing the information until selectively removed by the ticket holder.
