Retrieving a product via a coded surface

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

determining a print media identifier from the print medium using a sensor module of a mobile telecommunications device, the print media identifier having been linked to the product; and,

retrieving, using the mobile telecommunications device and the print media identifier, the product,

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,

the print medium is provided with coded data in a format, the coded data encoding information, at least some of the information being indicative of the print media identifier,

the method includes:

when the print medium is presented in a media feed path of the mobile telecommunications device, reading, using the sensor module, at least some of the coded data; and

determining, using the at least some read coded data, the print media identifier, and

the media feed path includes a printer of the mobile telecommunications device.

2. The method as claimed in claim 1 , wherein information associated with or representative of the product is at least one of: displayed on a display of the mobile telecommunications device; and printed on a print medium by a printer module of the mobile telecommunications device.

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

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

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

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

9. The method as claimed in claim 1 , wherein the format is a linear pattern.

10. The method as claimed in claim 1 , wherein the information is further indicative of a two-dimensional coordinate grid, and the format is a two-dimensional pattern.

11. The method as claimed in claim 10 , wherein the product is associated with a region of the print medium, the method including:

reading, using the sensor module, at least some of the coded data;

determining, using the at least some read coded data, a position of the sensor module relative to the print medium; and,

retrieving, if the determined position is within the region, the product.

12. The method as claimed in claim 1 , wherein the information is further indicative of a digital signature associated with the print media identifier, the method including:

determining, by reading at least some of the coded data using the sensor module, the digital signature; and

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

13. The method as claimed in claim 12 , wherein the digital signature includes at least one of: a random number; a secret-key digital signature; and a public-key digital signature.

14. The method as claimed in claim 1 , wherein a printer module of the mobile telecommunications device prints at least some of the coded data on the print medium.

15. The method as claimed in claim 1 , wherein the method includes paying for the product using the mobile telecommunications device.
