Automated transaction system with modular printhead having print authentication feature
First Claim
1. In a transaction terminal having 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 operations said terminal to enable a user to input the request for value indicia through said input means and to enable said printing means to print the requested value indicia on the article, an improved printing means for said transaction terminal comprising:
- said printing means being formed as a separate section in said terminal and having a printhead and a dedicated microprocessor for controlling said printhead contained therein;
first ink supply means for supplying a visible ink to said printhead;
second ink supply means for supplying an invisible, machine-readable ink to said printhead; and
said printhead microprocessor having interface means connected to said operating means of said terminal for receiving the value indicia request input to said terminal, and print program means for controlling said printhead to print the requested value indicia as a visible indicia with visible ink from said first ink supply means on said article, for deriving an authentication code which uniquely corresponds to the requested value indicia, and for controlling said printhead to print the authentication code as an invisible indicia with invisible ink from said second ink supply means on said article, whereby said printed visible value indicia can be subsequently verified as authentic by machine reading of said invisible authentication code and comparing the authentication code for correspondence to the value indicia.

Abstract
An automated transaction system employs a terminal for printing a value indicia, such as a postmark, on an article. The terminal contains a modular printer unit which has a printhead and a dedicated microprocessor physically permanently bonded together such that the printhead microprocessor cannot be physically tampered with without disabling the printhead. The modular printer unit includes a first supply of visible ink and a second supply of invisible ink, and an internal program for printing the value indicia with visible ink and an authentication code, which uniquely corresponds to the value indicia, with invisible ink. The invisible value indicia can be subsequently verified as authentic by machine reading of said invisible authentication code and comparing the authentication code for correspondence to the value indicia.

11. A modular printing section for use in a terminal comprising:
-
a printhead and a dedicated microprocessor for controlling said printhead physically permanently bonded together in said modular printing section such that said printhead microprocessor cannot be physically tampered with without disabling said printhead; means for removably mounting said modular printing section in an associated terminal; and said printhead microprocessor having interface means for establishing an operative connection with the associated terminal to receive a print request signal from said terminal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
