Barcodes with black stripes and numbers on a white background are everywhere. Barcodes can be found on various product packets in supermarkets, on top of various fruit packets on the supermarket, and on the products package purchased on Amazon and Flipkart.

Most people do not pay much attention to barcodes in everyday life or how smoothly they have made life easier. Despite the success stories of today's cutting-edge technologies, the barcode is a breakthrough in 20th-century technology. Barcodes can be called the revolution that brought about the revolution in the retail industry.

History

The history of the barcode began 70 years ago. The barcodes were first created by Bernard Silver and his friend Norman Joseph Woodland of the Drexel Institute in Philadelphia, in response to a need for a vendor to read the products on the shop.

A team led by American engineer George Lauer began building barcodes effectively with the creation of a Universal Product Code (UPC). The UPC scanner was first installed in 1974 in a supermarket in Ohio. On June 26, the same year, Wiggles' chewing gum was first performed on a scan of a product with a barcode.

The barcode prepared by Lawler is a one-dimensional set of 30 black vertical stripes and 29 thick white variants - in all 59 black and white bars. The rows represent numbers and they are printed below. Each pattern contains 95-bit binary code. The codes in these patterns are identified by passing over the light beam barcode that emanates from the scanner. They match the information in a database.

The popularity was very slow

Despite its many achievements, barcodes are still less popular than they are today. Retailers were initially reluctant to pay for scanners. They were not interested in connecting to cash flow technology. Moreover, they feared that all transactions would be accurately recorded and that if barcodes were substituted for price tags, they would be cheated. But by the 1980s, the world of barcode was slowly conquering the world. Neither Bernard Silver nor Norman Joseph Woodland nor George Lore could see the journey directly.

Use of barcodes

Organizations that sell a variety of products use barcodes for a variety of purposes. Based on that, barcodes have different classifications. The ISBN barcode is displayed above the printed books. Newspapers, magazines and CDs are coded as IISBN. Barcode classifications are also based on countries.

Codes that change over time

Today, barcodes are very popular worldwide. Barcodes are issued by specialist international agencies. With the advent of new computer technologies, barcodes have become almost everywhere.

There have been many changes to barcodes. But the basics remain. Barcodes can be found on everything from product details to bands and blood samples to a hospital-born child.

Recently developed 2D matrix codes have much wider use possibilities. QR codes are like that. Rectangles, puzzles, colors, and geometric shapes are all used to convey more information. The new barcodes have a variety of uses, including boarding passes, online banking, information exchange between mobile phones, and the use of rented bikes.
