1D Barcode

What is 1D Barcode?

A 1D barcode, also known as a linear barcode or a one-dimensional barcode, is a barcode that is composed of vertical bars and spaces of varying widths. The bars and spaces represent a series of numbers, letters, or other characters that can be read and decoded by a barcode scanner.

1D barcodes are widely used in a variety of applications, such as inventory management, asset tracking, and retail product labeling. They can be printed on a wide range of materials, including paper, plastic, and metal. The most common types of 1D barcodes include Code 39, Code 128, and UPC/EAN. Code 39 is a widely used barcode standard that supports alphanumeric characters and is often used in industrial and healthcare applications. Code 128 is a high-density barcode that can encode a large amount of data in a small space and is commonly used in logistics and shipping applications. UPC (Universal Product Code) and EAN (European Article Number) are barcode standards commonly used for product labeling in the retail industry. One limitation of 1D barcodes is that they can only encode a limited amount of data, typically up to 20-30 characters. To encode larger amounts of data, 2D barcodes such as QR codes are often used.
