Infrared scanner with two-dimensional code identification function

Abstract

The invention discloses an infrared scanner with a two-dimensional code identification function, and relates to the field of two-dimensional code security. The scanner comprises a substrate, a two-dimensional code sticker, a back sensing probe and an alerter; the back sensing probe is connected with the alerter, the two-dimensional code sticker is stuck to the substrate, and the back sensing probeis fixed between the substrate and the two-dimensional code sticker; a frame is arranged around the substrate, and an infrared camera is arranged on the frame; when the two-dimensional code sticker of a store is torn apart, the back sensor probe sends a sensing signal to a sensor, and the sensor transmits the sensing signal to the alerter to give an alarm; when other two-dimensional stickers arestuck to the two-dimensional code sticker of the store, the shooting direction of the infrared camera faces the substrate; due to the fact that wavelength of an infrared ray is long, it can be seen that multiple layers of the two-dimensional code stickers exist on the substrate through the first layer of the two-dimensional code sticker. Accordingly, whether the two-dimensional code is simulated by lawbreakers or not can be known.

Description

technical field [0001] The invention relates to the field of two-dimensional code security, in particular to an infrared scanner with a two-dimensional code identification function. Background technique [0002] Two-dimensional barcodes / two-dimensional codes record data symbol information with black and white graphics that are distributed on a plane (two-dimensional direction) according to a certain pattern with a specific geometric figure; in code compilation, they are skillfully used to form the internal logic basis of the computer. The concept of the "0" and "1" bit stream in the system uses several geometric shapes corresponding to the binary to represent the text and numerical information, which can be automatically read by image input equipment or photoelectric scanning equipment to realize automatic processing of information: it has a barcode Some common features of the technology: each code system has its specific character set; each character occupies a certain widt...
