Description

barcode reader

technical field

The utility model relates to a barcode reading device, in particular to a barcode reading device capable of reading one-dimensional and two-dimensional barcodes.

Background technique

Barcodes can be divided into two categories: 1D or linear barcode and 2D barcode. One-dimensional barcodes, such as UPC barcodes, encode data by interlacing multiple black lines of different widths and white spaces to represent corresponding letters, numbers, etc. Now every product sold is affixed with a one-dimensional barcode, so that the product can be quickly identified at the checkout or in every link of the supply chain.

Two-dimensional barcodes, such as QR codes (quick response code), use graphics and shapes (such as hexagons, squares, and dots) to encode data, which provide no direction and have greater data density and Capacity, can be used to store form, text and image data, so it is suitable for storing product discount information.

Due to the different mechanisms of the barcode readers used for 1D barcodes and 2D barcodes, there are currently more than one checkout counters on the market that are equipped with scanners for reading 1D barcodes and 2D barcodes respectively, but this causes wires Problems of winding, power consumption and space occupation.

Secondly, when the product is checked out, the consumer will hand over the product to the clerk to read the one-dimensional barcode; at the same time, if the consumer has preferential information encoded with the two-dimensional barcode, he must also read the two-dimensional barcode Hand over to the clerk for discount; however, as mobile devices are widely used, most of the 2D barcodes with discount data provided by merchants are displayed on the mobile device; every time you check out, you must hand over the mobile device to the clerk for 2D barcode In addition to causing inconvenience to both parties, the reading of the barcode may also cause the mobile device to be damaged due to dropping during the transfer process.

Utility model content

In view of the prior art, the utility model provides a barcode reading device capable of reading at least two barcodes with different codes, so as to reduce the inconvenience in use.

According to the utility model, a barcode reading device is provided, which includes a polygonal body and a plurality of barcode reading units; one surface of the polygonal body is provided with a first window, and the other surface is provided with a second window; the barcode reading units are respectively It is accommodated in the chamber of the polygonal body; one of the aforementioned barcode reading units reads the barcode through the second window, and at least one of the aforementioned barcode reading units reads the barcode through the first window.

The utility model arranges a plurality of barcode reading units on different surfaces of the polygonal body, so shop assistants and consumers can individually place the barcodes close to the barcode reading units on different surfaces of the polygonal body to save checkout time and reduce costs.
