1D-barcodes

Why 1D barcodes are still in use?

Today, barcode scanners are no stranger to supermarkets, retail stores, fashion shops, shoes, industrial parks, hospitals, express delivery… because they bring convenience as well as convenience such as absolute accuracy, making it easier for users to manage sales and inventory.

Barcodes operate based on 1D or 2D technology, manufacturers will research and produce many types of products, but not everyone knows about the uses and functions of each type. In this article, we would like to share some information and operating principles of these two technologies to help you better understand barcode technology to make the best choice.

What are 1D barcodes?

One-dimensional (1D) barcodes are also known as linear barcodes. A first-generation “one-dimensional” barcode is made up of lines and spaces of different widths that produce specific patterns. Linear barcodes – such as UPC, EAN barcode and GS1-128 are one-dimensional barcodes that contain a series of vertical black bars and white spaces that identify a set of numbers or letters.

A barcode is a series of alternating parallel bars and spaces arranged according to a defined encoding rule to represent a numerical code (or alphanumeric data) in a scanner readable form.

From a long time ago, in order to manage goods and products more efficiently for a large range, people invented barcodes and codes.

Should we use 1D barcodes in 2021?

Over the years of development, the types of barcodes and codes have become more diverse, depending on the types of information to be encoded as well as the needs of use.

Typically, we have 1D codes, also known as 1-dimensional codes, which are commonly found codes on product packages and boxes with the shape of long horizontal lines like this. 1D codes encode very little information, only numbers.

While 1D codes are limited in size and the data is encoded horizontally, increasing the data content equals increasing the width of the code, and in curved products, when printing or labeling 1D codes becomes more difficult, more difficult for the device to scan. In addition to being able to print on small areas, 2D codes can also be scanned from up to 15 meters away.

When scanning, 1D barcode scanners use scanning technology that cuts across the barcode’s stripes, usually 1D scanners use a CCD eye or a laser with a long and narrow beam of light.

What is CCD?

CCD is a technology for scanning highly durable codes that can scan small lines on rough surfaces. The laser eye can scan codes on curved and distant surfaces, scanning in motion. Laser for stronger and faster scanning. However, like the eyes that read on CD and DVD players, after a while, the laser eyes will weaken and give less effective scanning.

One limitation is that with 1D scanners, we can only scan the code at 1 angle, there are also more advanced 1D scanners with multi-ray scanning structures but the cost is often quite expensive.

The most importantly we must determine the needs and scope of use. For example, product management of ordinary retail stores, fashion shops, libraries… can simply use a linear 1D laser barcode scanner.
