Method of generating a two-dimensional code with a constant background pattern
First Claim
Patent Images
1. A method of generating a two-dimensional code that comprises the steps of:
- allocating a number of background entries on a carrier for a constant background pattern detectable by a reader;
printing background dots on the carrier to define the background pattern so that the background pattern includes an orientation component, detectable by a reader and having an asymmetric shape so as to indicate an orientation of the carrier;
allocating a number of data entries on the carrier for a data area in which data represented by the two-dimensional code is carried; and
printing an array of data dots, detectable by the reader, in the data area to represent said data.

Abstract
A method of generating a two-dimensional code includes the steps of allocating a number of background entries on a carrier for a constant background pattern detectable by a reader. Background dots are printed on the carrier to define the background pattern. A number of data entries are allocated on the carrier for a data area in which data represented by the two-dimensional code is carried. An array of data dots, detectable by the reader, is printed in the data area to represent said data.
