Abstract

A system of retrieving a product using a print medium with a print media identifier linked to a product. A mobile telecommunications device with a sensor module for determines the print media identifier from the print medium such that the product is retrieved using the mobile telecommunications device and the print media identifier. The print medium is provided with first coded data in a first format and second coded data in a second format. The first coded data encodes first information and the second coded data encodes second information. The first information is indicative of the print media identifier and of size and orientation data of the print medium. The first format is a linear pattern. At least some of the second information is indicative of the print media identifier and a two-dimensional coordinate grid. The second format is a two-dimensional pattern, the first and second coded data each being encoded in a plurality of tags printed on the print medium. Each tag has a structure that includes a target and the first and second coded data. The targets are sensed by the sensor module to determine the presence of the tags.

Claims

1. A system of retrieving a product using a print medium, the system comprising:

a print medium with a print media identifier, the print media identifier being linked to a product;

a mobile telecommunications device with a sensor module for determining the print media identifier from the print medium such that the product is retrieved using the mobile telecommunications device and the print media identifier;

wherein,

the print medium is provided with first coded data in a first format and second coded data in a second format, the first coded data encoding first information and the second coded data encoding second information, the first information being indicative of the print media identifier and of size and orientation data of the print medium, the first format being a linear pattern, at least some of the second information being indicative of the print media identifier and of a two-dimensional coordinate grid, the second format being a two-dimensional pattern, the first and second coded data each being encoded in a plurality of tags printed on the print medium, each tag having a structure which includes a target and the first and second coded data, the targets being sensed by the sensor module to determine the presence of the tags.

2. The system as claimed in claim 1, wherein the mobile telecommunications device has a display and a printer module and the product has associated information, the mobile telecommunications device being configured to show the associated information on the display or print the associated information on a print medium with the printer module of the mobile telecommunications device.

3. The system as claimed in claim 1, wherein the product is a sample product.

4. The system as claimed in claim 1, wherein the product is required to be purchased.

5. The system as claimed in claim 1, wherein the product is at least one of:

an application;

a utility;

used to obtain a service;

a game;

an accessory;

an image;

audio;

video;

a document;

a mobile phone ringtone;

mobile phone wallpaper;

a database;

data;

a program;

a program state;

an access token;

a ticket;

a voucher; and

a map.

6. The system as claimed in claim 1, wherein the product is retrieved from a database and the database is at least one of:

stored locally at the mobile telecommunications device; and

stored remotely at a server.

7. The system as claimed in claim 1, wherein one or more products are retrieved periodically by the mobile telecommunications device.

8. The system as claimed in claim 1, wherein the sensor module is used to link the product to the print media identifier.

9. The system as claimed in claim 1, wherein the information is further indicative of a digital signature associated with the print media identifier, the mobile telecommunications device being configured to determine the digital signature by reading at least some of the coded data using the sensor module;

and

retrieving, if the digital signature is authentic, the product.

10. The system as claimed in claim 9 wherein the digital signature includes at least one of:

a random number;

a secret-key digital signature; and

a public-key digital signature.

11. The system as claimed in claim 2, wherein a printer module of the mobile telecommunications device prints at least some of the coded data on the print medium.

12. The system as claimed in claim 1, wherein the product is purchased using the mobile telecommunications device.

13. The system as claimed in claim 1, wherein the coded data is restricted to a region of the print medium, the region being coincident with human readable images or information associated with the product.
