Who Invented The Barcode Scanner


Early Developments in Barcode Technology

In the early 1940s, as World War II was raging, the need for an automated system to track and identify products became increasingly apparent. This led to the birth of barcode technology, which would revolutionize the way businesses track and manage their inventory.

During this time, a group of engineers and scientists was tasked with finding a solution. They explored various methods, including using radio waves and ultraviolet light, but these proved to be impractical or too expensive.

It was not until the 1950s that the first prototypes of barcode technology began to emerge. The initial concept involved encoding information using patterns of lines and spaces that could be easily scanned and interpreted by a machine.

One of the earliest barcode systems developed during this period was the bull’s eye barcode, patented by David J. Collins in 1952. This design consisted of a series of concentric circles, with each circle representing a different digit. Although it was a step in the right direction, it was not widely adopted due to technical limitations.

In 1959, a breakthrough occurred when the National Association of Food Chains (NAFC) sponsored a project to find a more practical barcode solution. This project brought together industry leaders such as RCA, IBM, and the Uniform Grocery Product Code Council (UGPCC).

It was during this project that the idea of using a linear barcode, resembling the barcode systems we are familiar with today, was proposed. This concept involved using a series of varying width parallel lines to represent the encoded information.

Throughout the 1960s, further developments in barcode technology were made. Norman Joseph Woodland and Bernard Silver, two inventors who would play a crucial role in the invention of the barcode scanner, began working on creating a barcode that could be easily read by a machine.

The early developments in barcode technology laid the foundation for modern barcode systems. Although the prototypes developed during this time were rudimentary compared to today’s sophisticated scanners, they were an important step towards revolutionizing the way products are tracked and identified.

The Invention of the First Barcode Scanner

While barcode technology was taking shape in the 1960s, the invention of the barcode scanner was the key to unlocking its potential. This breakthrough device would allow businesses to efficiently scan and decode barcode information, leading to the widespread adoption of barcode systems.

Bernard Silver and Norman Woodland, who had been working on barcode technology, filed a patent application for their invention in October 1949. The patent described a method for automatically reading codes, now known as barcodes, using light-sensitive elements to detect the variations in width in the pattern of lines.

However, it wasn’t until 1973 that the first practical barcode scanner was created. David Collins, a fellow engineer at RCA, developed the first commercially successful barcode scanner, known as the “Wand.” This handheld device used a light source and a photoelectric cell to read the barcode lines and convert them into electrical signals.

The Wand was a significant improvement over previous barcode scanning attempts because it could read barcodes from varying distances and angles, making it a versatile tool for businesses. It allowed for rapid and accurate data collection, helping companies streamline their inventory management processes.

The Wand’s success prompted the development of other barcode scanners by companies like IBM and Monarch Marking Systems. These early scanners utilized different technologies, including laser beams and LED lights, to read barcode information.

Shortly after the release of the Wand, the Universal Product Code (UPC) became the standard barcode system used in the retail industry. This further accelerated the adoption of barcode scanners, as both retailers and manufacturers recognized the benefits of using a standardized, machine-readable system.

By the late 1970s, barcode scanners were widely used in various industries, from retail and logistics to healthcare and manufacturing. The invention of the barcode scanner revolutionized inventory management and paved the way for improved efficiency and accuracy in data collection.

Today, barcode scanners have become even more advanced, with the emergence of 2D barcodes and wireless scanning capabilities. From fixed-point scanners to handheld devices and mobile apps, barcode scanners continue to play a critical role in various applications, enabling businesses to track, trace, and manage their products with ease.

The Role of Bernard Silver and Norman Woodland

Bernard Silver and Norman Woodland, two visionary inventors, played a crucial role in the development of barcode technology. Their groundbreaking work laid the foundation for the barcode systems we rely on today. Here’s a closer look at their contributions:

In the late 1940s, while attending graduate school at Drexel Institute of Technology (now Drexel University) in Philadelphia, Bernard Silver overheard a conversation between a grocery store owner and the dean. The store owner expressed his frustration with manually entering product information, igniting Silver’s curiosity about finding an automated solution.

Silver shared his idea with his friend and fellow graduate student, Norman Woodland. Together, they began experimenting with various methods to create a system that could automatically capture and decode product information.

Their breakthrough came when Woodland drew a series of parallel lines in the sand on a Florida beach, inspired by Morse code and its ability to represent information through a sequence of dots and dashes. This concept sparked the idea for a barcode system using lines of varying widths to encode data.

In October 1949, Silver and Woodland filed a patent application for their invention, titled “Classifying Apparatus and Method.” The patent described a method for capturing and decoding coded information using light-sensitive elements and pattern recognition techniques. This laid the foundation for the first barcode system.

Although their patent was granted in 1952, it took several more years for the technology and infrastructure to catch up to their vision. It wasn’t until the 1970s that barcode systems and barcode scanners became commercially viable and started to revolutionize industries worldwide.

Throughout their lives, both Silver and Woodland made significant contributions to the barcode industry. Woodland continued to work on barcode and scanning technologies, ultimately holding over 25 patents related to the field.

In recognition of their pioneering work, Silver and Woodland received numerous awards. In 1991, they were granted the prestigious National Medal of Technology and Innovation by President George H.W. Bush.

The contributions of Bernard Silver and Norman Woodland in the field of barcode technology cannot be overstated. Their inventive spirit and determination laid the groundwork for one of the most transformative innovations of the modern era, changing the way we track and manage products across various industries.
