Description

Bar code scanning method

The invention relates to a barcode scanning device and a method thereof, in particular to a barcode scanning device and method for scanning an optical barcode label to obtain product data represented by a barcode label.

The Bar Code uses tens of millions of products around the world with the title of "Global ID Card". It scans the barcodes on the product to identify the identity and read the data. In order to identify the product and improve the liquidity of the product, the product can be marketed all over the world.

With the frequent international trade and the increasingly fine division of products, the circulation of products between countries is huge, so the control of product logistics or product trading behavior becomes very important, and the use of readable labels is Simple and accurate control tools.

The conventional technology for reading labels is mainly an optical barcode label. Generally, a product will have a code label at an appropriate position on the outer surface or the outer package. In practical applications, the barcode label is illuminated by an infrared or visible light source, and the black stripe is black. Light is absorbed, and a white empty symbol reflects the light, which is then translated into an electronic pulse by a scanner. Then, by means of a built-in or external decoder, the electronic pulse is translated into a binary code by a mathematical program, and the decoded data information is transmitted to a personal computer or a controller to obtain product data represented by the barcode label.

However, the conventional scanners are operated in a hand-held manner, and the operator must hold the scanner to scan the product by hand, which is quite inconvenient.
