Patent

CA 1296809

A B S T R A C T A transaction terminal has input means for inputting a request for printing a value indicia on an article, printing means for printing the requested value indicia on the article, and operating means for operating said terminal to enable a user to input the request for value indicia through the input means and to enable the printing means to print the requested value indicia on the article. In an improved printing means for the transaction terminal, the printing means is formed as a separate section in the terminal and has a printhead and a dedicated microprocessor for controlling the printhead contained therein. First ink supply means are provided for supplying a visible ink to the printhead. Second ink supply means are provided for supplying an invisible, machine-readable ink to the printhead. The printhead microprocessor has interface means connected to the operating means of the terminal for receiving the value indicia request input to the terminal, and print program means for controlling the printhead to print the requested value indicia as a visible indicia with visible ink from the first ink supply means on the article, for deriving an authentication code which uniquely corresponds to the requested value indicia, and for controlling the printhead to print the authentication code as an invisible indicia with invisible ink from the second ink supply means on said article. The printed visible value indicia can be subsequently verified as authentic by machine reading of the invisible authentication code and comparing the authentication code for correspondence to the value indicia.
