What does the bar code on the goods mean?

In the modern market economy, the bar code on commodities is one of the keys to commodity management and sales. Usually, the barcode on a commodity contains the basic information of the commodity, such as its name, price, production date, manufacturer, etc. , and a unique code for identifying and tracking goods. Through bar codes, consumers can conveniently inquire about commodity information and make purchases, and at the same time, it is convenient for merchants to manage inventory and sales.

Barcodes can be divided into one-dimensional codes and two-dimensional codes. One-dimensional bar code usually consists of a series of black and white lines, which represent commodity information in the form of numbers and letters; QR code can be scanned by mobile phone to get more comprehensive information, such as websites, pictures and texts. In addition to the application in commodity sales, bar codes are also widely used in logistics, medical care, ticketing, e-commerce and other fields. In the field of e-commerce, bar codes are not only widely used in commodities, but also in payment, express delivery, logistics and other links.

With the advent of the digital age, bar code technology has been more widely used. In recent years, with the development and application of Internet of Things technology, bar codes have been continuously upgraded and innovated, and new identification technologies such as RFID and NFC have emerged. In the future, with the further application of artificial intelligence technology and the deepening of information management, barcode technology will be more efficient, accurate and convenient, which is expected to further enhance market vitality and economic growth.
