The invention of barcodes provided a solution to this problem. Subsequently the POS system was developed, in which the price of an item of merchandise was displayed on the cash register automatically when the barcode on the item was scanned by an optical sensor, and information on the item was sent to a computer at the same time. As the use of barcodes spread, however, their limitations became apparent as well. The most prominent was the fact that a barcode can only hold 20 alphanumeric characters or so of information.
The modern-day QR Code consists of 7 parts. Each of these parts creates a sort of pixel pattern that looks similar to a crossword puzzle. Each element has a specific purpose that conveys certain information through the Code such as the print direction, timing, error tolerance, and empty spaces to differentiate the Code from what surrounds it. These days, the majority of QR Codes are scanned with a smartphone. There are tons of free apps for QR scanning for both Android and iOS devices(also with the camera). Most often, you simply open the app and it automatically scans the QR Code with the touch of a button. The uses of QR Codes surpasses the bazillion mark. Seriously. We’ve got a comprehensive guide with examples but we’ll summarize a few examples below. Discover even more info on orderific.com.
As American dissatisfaction with waiting in line grew throughout the 50s and 60s, IBM set to work in the early 1970s to revisit the earlier patented technology. And IBM, in coordination with the grocery industry, developed the vertically-aligned UPC barcode we know today. The idea was to create a universal system of product identification and processing. A system that didn’t rely on manually entering numbers anywhere, but on fast optical scanning. Point-of-sale (POS) systems and scanners were required to scan and process the new UPC barcodes. Those were sold and distributed by IBM. By the late 1970s, checkout lines had sped up 40%. Throughout the 80s, thousands upon thousands of grocery and retail stores adopted the technology. By the 2000s, the barcode business had a value of around $17 billion. Billions of items are now scanned every day in every industry across the world.
