Method of generating a two-dimensional code with a constant background pattern

摘要

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.
