Abstract

The embodiment of the invention provides a device and a method for forming a double-layer quick response matrix code symbol. The method comprises steps of adopting a double-layer pattern structure, sequentially arranging a bottom layer plane, a gap and a top layer plane from bottom to top, and forming a first quick response matrix code symbol on a bottom layer pattern by penetrating through the gap from the left boundary of the top layer pattern and a first visual angle aligned with the left boundary of the bottom layer pattern; penetrating through the gap from the right boundary of the top pattern, and forming a second quick response matrix code symbol on the bottom pattern at a second visual angle aligned with the right boundary of the bottom pattern; reading the first information and the second information through the first quick response matrix code symbol and the second quick response matrix code symbol respectively; and if the first quick response matrix code symbol and the second quick response matrix code symbol are different, i.e., the first information and the second information represent two pieces of different information, reading two pieces of different information attwo different visual angles on the premise of not changing the area of the bottom layer pattern.

Description

technical field [0001] The invention belongs to the field of data recording carriers, in particular to a device and method for forming double-layer quick response matrix code symbols. Background technique [0002] Quick Response Matrix Code is a digital data encoding format that can represent information of various data types such as numbers, letters, Chinese characters, and binary strings. The quick response matrix code symbol refers to the picture corresponding to the quick response matrix code symbol. Quick response matrix code symbols can be quickly recognized by mobile terminals and are used in identification, transactions, logistics, advertising and other fields. [0003] Typically, only one Quick Response Matrix Code symbol can be displayed in the same area. If you want to display two QRM code symbols in the same area, you need to occupy twice the area, which makes the application more cumbersome, and when the mobile terminal recognizes one of the QRM code symbols, ...
