Introduction to Barcodes
A barcode is a graphical representation of data, where the data is encoded in the widths and spacings of parallel lines. Barcodes are widely used in product management, library management, ticketing systems, and many other fields, as their convenience and accuracy make them an important tool for modern data collection.
Origin of Barcodes
The concept of barcodes can be traced back to the late 1940s. In 1948, Bernard Silver and Norman Joseph Woodland, at the Drexel Institute of Technology in Philadelphia, proposed the idea of barcodes. They were commissioned by a local food chain to research how to automatically read product information and speed up the checkout process. Inspired by Morse code, Woodland combined dots and lines to create an early version of the barcode.
In 1966, the first commercial barcode system was deployed in the railroad freight industry. In 1974, the world's first barcode scanner was installed at a Marsh's Supermarket in Ohio, USA, and it scanned the first product - a pack of Wrigley's chewing gum. This event marked the widespread adoption of barcodes in commercial applications.
Advantages of Barcodes
  • High Efficiency and Speed: Barcode scanning is fast, significantly improving the efficiency of product checkout, inventory management, and other processes.
  • High Accuracy: Barcodes can read information accurately, avoiding the errors that may occur with manual data entry.
  • Low Cost: Barcode printing and scanning equipment is inexpensive, and maintenance is simple, making it suitable for large-scale applications.
  • High Universality: Barcodes have become an international standard, allowing for global use and facilitating cross-border trade and logistics.
  • Large Data Storage Capacity: Although traditional one-dimensional barcodes have limited data capacity, two-dimensional barcodes (such as QR codes) can store more information, including text, URLs, and others.
Disadvantages of Barcodes
  • Susceptibility to Damage: Barcodes can be easily damaged by wear, creases, and other factors, affecting their readability.
  • Limited Data Capacity: Traditional one-dimensional barcodes have a limited data capacity, typically only able to store numbers or letters, and unable to store more complex data.
  • Strong Visual Dependence: Barcodes must be within the visible range to be scanned by a reader, and their performance is poor on transparent packaging or reflective surfaces.
  • Difficulty in Data Update: Once a barcode is generated, the data content is difficult to change, and a new barcode must be generated.
