When were barcodes and scanners invented?

### Invention of Barcodes and Scanners.

Barcodes and scanners were invented in the early 1970s. The first barcode, which was a set of concentric circles, was patented in 1952 by Joseph Woodland and Bernard Silver. However, it was not until the early 1970s that the barcode technology we are familiar with today was developed.

#### Step 1: Barcode Development.

In 1973, the first UPC (Universal Product Code) barcode was scanned on a pack of Wrigley's chewing gum in a supermarket in Ohio. This event marked the beginning of the barcode revolution in the retail industry.

#### Step 2: Barcode Standardization.

Following the successful scanning of the first UPC barcode, efforts were made to standardize barcode technology. In 1974, the Uniform Code Council (now GS1 US) was established to set guidelines for the use of barcodes on products.

#### Step 3: Scanner Development.

Around the same time as the standardization of barcodes, laser scanners were developed to read the codes quickly and accurately. The first laser scanner was installed in a Marsh supermarket in 1974.

#### Step 4: Adoption in Industries.

By the late 1970s and early 1980s, barcodes and scanners had become widely adopted in various industries, including retail, manufacturing, and healthcare. They revolutionized inventory management, sales tracking, and supply chain operations.

#### Step 5: Evolution of Barcodes.

Since their invention, barcodes have evolved to include different types such as QR codes and RFID tags. These advancements have further enhanced the efficiency and accuracy of data collection and tracking.

In conclusion, barcodes and scanners were invented in the early 1970s and have since become an indispensable part of modern business operations. Their invention revolutionized the way goods are tracked, inventoried, and sold, leading to increased efficiency and accuracy in various industries.
