ABSTRACT:
An apparatus for performing computer-based operations includes a computer system which includes at least one computer. A printer is connected to the computer system and is capable of printing with visible ink and invisible ink to generate a sheet of media printed with visible information and invisible depictions of coded data on receipt of initial print instructions from the computer system. The computer system is programmed to generate the invisible depictions such that the coded data represents instructions capable of being executed by the computer. A sensor is capable of detecting the invisible depictions and is configured to generate a signal carrying said coded data. The sensor is connected to the computer system, which is configured to decode the coded data and to execute the instructions.
