A 1D (one-dimensional) barcode, also known as a linear barcode, represents data using a series of parallel lines and spaces of varying widths. It typically holds 20 to 30 characters of basic information, like an item number or SKU, and must be scanned by a laser or optical reader.
The most widely used 1D barcode formats include:
- UPC (Universal Product Code): Commonly found on retail packaging in North America.
- EAN (European Article Number): The standard global retail product code used internationally.
- Code 128: A versatile, high-density barcode used extensively in logistics and shipping.
- Code 39: Often used for name badges, inventory, and industrial applications.
- ITF-14: Used on the outer packaging (corrugated cardboard) of shipped goods
a standard 1D barcode system relies on exactly those core components to create, read, and manage barcode data. [1]
Here are the essential elements that make up the system:
- Barcode Printer: Used to design and print the barcodes onto labels or tags. These are typically specialized thermal printers (direct thermal or thermal transfer) rather than standard office printers.
- Scanner: The hardware used to read the printed barcodes. Scanners decode the pattern of varying widths and spaces and send that data to your computer or system.
- Barcode Labels/Paper Rolls: The physical medium where the barcode is printed. For inventory or retail, these are usually adhesive labels.
- Label Design Software: The application you use on your computer to format the barcode, input product data, and send it to the printer.
- Barcode Generation/Management System: Often a POS (Point of Sale) or inventory management system that assigns a unique number to each item, links the barcode to that item in a database, and updates stock when scanned.
