The barcode on the trademark, also known as the product barcode, is a universal barcode used to identify products. It consists of a set of regularly arranged bars, spaces and their corresponding characters. These bars, spaces and characters have specific meanings and encoding rules.

Trademark barcodes usually consist of numbers or letters, with the most commonly used formats being EAN and UPC codes. The EAN code is a popular barcode in continental Europe, while the UPC code is mainly used in the United States and Canada.

The encoding rules for trademark barcodes are formulated by international standards organizations to ensure universality on a global scale. Trademark barcodes not only facilitate merchants to scan and identify goods when selling them, but also facilitate consumers to obtain product information and price information by scanning barcodes when purchasing goods.

In trademark barcodes, different barcode symbols and barcode codes correspond to different product information, which includes product categories, specifications, packaging forms, etc. Merchants can use trademark barcodes to manage their own products, improve sales efficiency, and also better manage inventory and conduct data analysis.

In short, the barcode on a trademark is an important identifier that can help merchants and consumers better manage products and obtain product information, while also improving business efficiency and accuracy.
