Abstract

A method of printing first information using a mobile telecommunications device and retrieving further information. The method comprises the steps of: providing a print medium having a linear data track and a two-dimensional coding pattern; printing the first information; automatically reading and decoding the data track during printing to determine a print media identifier; communicating the print media identifier to a computer system; interacting with the print medium and sensing the coding pattern; decoding the sensed coding pattern to determine the print media identifier and a two-dimensional coordinate position; and retrieving further information.

Claims

1. A method of printing first information on a print medium using a mobile telecommunications device and retrieving further information, said method comprising the steps of:

providing the print medium having a linear data track extending along a side of the print medium and a two-dimensional coding pattern disposed across a face of the print medium, said linear data track identifying at least a print media identifier, said two-dimensional coding pattern identifying at least the print media identifier and a plurality of locations in a two-dimensional coordinate grid;

printing the first information onto the print medium using a printer module of the mobile telecommunications device;

automatically reading the data track during said printing using an optical encoder positioned in a media path of the printer module;

decoding the read data track to determine the print media identifier;

communicating the print media identifier to a computer system, thereby causing the computer system to associate the print media identifier with the printed first information so as to create a linked page description;

interacting with the print medium and sensing part of the two-dimensional coding pattern using a sensor module of the mobile telecommunications device;

decoding the sensed coding pattern to determine the print media identifier and a two-dimensional coordinate position; and

retrieving, using the mobile telecommunications device, the decoded coded pattern and the linked page description, at least one of;

the first information and second information identified by said linked page description.

2. The method of claim 1, wherein said retrieved linked first information or said second information is displayed on a display screen of the mobile telecommunications device.

3. The method of claim 1, wherein the two-dimensional coding pattern encodes a digital signature associated with the print media identifier, said the method comprising the further step of:

determining the digital signature from the sensed coding pattern; and

performing said retrieving step only if the digital signature is authentic.

4. The method of claim 3, wherein the digital signature includes at least one of:

a random number;

a secret-key digital signature; and

a public-key digital signature.

5. The method of claim 1, wherein said linear data track is self-clocked.

6. The method of claim 1, wherein said print medium further comprises a clock track extending alongside said data track.

7. The method of claim 1, wherein said linear data track is disposed on a face of said print medium opposite the face on which said two-dimensional coding pattern is disposed.

8. The method of claim 1, wherein said first information represents a bill.

9. A system for printing first information on a print medium and retrieving further information, said system comprising:

(A) a print medium having a linear data track extending along a side of the print medium and a two-dimensional coding pattern disposed across a face of the print medium, said linear data track identifying at least a print media identifier, said two-dimensional coding pattern identifying at least the print media identifier and a plurality of locations in a two-dimensional coordinate grid;

(B) a mobile telecommunications device comprising;

a media path for receiving the print medium;

a printer module for printing the first information onto the print medium;

an optical encoder positioned in the media path for automatically reading the data track during said printing;

a processor for decoding the read data track and determining the print media identifier;

a sensor module for interacting with the print medium and sensing part of the two-dimensional coding pattern;

a transceiver for;

communicating the print media identifier to a computer system, thereby causing the computer system to associate the print media identifier with the printed first information so as to create a linked page description; and

retrieving at least one of;

the first information and second information identified by said linked page description in response to the said sensor module interacting with said print medium; and

a display for displaying at least one of;

the retrieved first information and the second information.

10. The system of claim 9, wherein said sensor module comprising an optically imaging pen or stylus.
