Problems solved by technology

[0002] At present, the traditional two-dimensional code is printed on the surface of the product packaging material by ordinary ink. This kind of two-dimensional code is exposed on the surface of the product and can be identified in any state. Yes, this ordinary printed two-dimensional code does not have identification Restrictions and anti-counterfeiting capabilities, which limit the ability of QR codes in product anti-counterfeiting; at the same time, exposed QR codes destroy the entire aesthetic design of product packaging

Abstract

The invention relates to the two-dimensional code technology field, and concretely relates to an irreversible and invisible two-dimensional code. The irreversible and invisible two-dimensional code comprises a two-dimensional code body which can perform color development irreversibly according to temperature or pressure change. The irreversible and invisible two-dimensional code is invisible or partly invisible at a normal state, and can emerge only in specific conditions. The two-dimensional code is irreversible, the two-dimensional code is unrecoverable after color development in specific conditions, and the novelty and the anti-counterfeiting ability of the two-dimensional code are raised.

Description

technical field [0001] The invention relates to the technical field of two-dimensional codes, in particular to an irreversible invisible two-dimensional code. Background technique [0002] At present, the traditional two-dimensional code is printed on the surface of the product packaging material by ordinary ink. This kind of two-dimensional code is exposed on the surface of the product and can be identified in any state. Yes, this ordinary printed two-dimensional code does not have identification Restrictions and anti-counterfeiting capabilities, which limit the ability of two-dimensional codes in commodity anti-counterfeiting; at the same time, the exposed two-dimensional codes destroy the entire beautiful design of commodity packaging. This patent proposes an invisible two-dimensional code using irreversible heat-sensitive or pressure-sensitive materials. Compared with traditional two-dimensional codes, this process is more advanced. Contents of the invention [0003] ...
