They can be used in all industries across the globe, enhance marketing efforts and even have personal uses. Using a combination of spacing as a type of Matrix Barcode a 2-D Barcode , when a QR Code is scanned, it conveys a wide multitude of information. QR Codes have a wide range of uses across all types of industries such as retail, marketing, and logistics. While QR Codes and Barcodes are similar in practice, QR Codes contain more information because they have the ability to hold information both horizontally and vertically.
Barcodes only use horizontal information. While Barcodes work wonderfully for situations like scanning supermarket items, QR Codes have a much higher capability of transferring information, likely what has made them increasingly popular due to their versatility. Like the development of many technologies, QR Codes were created out of necessity. QR Codes actually started out as Barcodes with their typical purpose: for supermarkets. In the s, Japan was experiencing a wave of economic growth. Supermarkets expanded from selling just food items to adding in clothing and a versatile range of other commodities.
So, they basically realized that they needed a way to keep track of everything. Before Barcodes existed, cashiers had to manually enter individual items can you imagine?!
Due to the health issues created as a result of these heavily repeated actions like carpal tunnel syndrome, supermarket managers knew they needed to find a solution. As a result of the growing demand for technology to lighten the burden on supermarket cashiers, a POS system was created. It was basically the newborn baby version of a Barcode that allowed for the scanning of individual items to be registered by a computer.
Supermarkets then faced another obstacle: Barcodes could only store up to around 20 alphanumeric characters of information and functioned with one dimension one direction of coding.
They were contacted by supermarkets who realized the limits of these Barcodes and sought a way to make them more versatile and contain more information through the development of a 2-D Code two directions of coding. With only two team members, Hara first came up with the idea of the square, because their research showed that it was an easily distinguishable shape.
This shape additionally allowed for both horizontally and vertically Coded information. A further advantage was that this also boosted the speed at which this information could be read up to 10x faster than Barcodes. Scanning a QR code using your device is straightforward: Open the QR reader application or the camera on your smartphone. Point it at the QR code — you should be able to point your camera from any angle and still receive the necessary information.
The data will be instantly shown on screen — for instance, if the QR code contains contact details, your phone should instantly download these. Are QR codes safe? Do QR codes collect my personal information and data? Can someone hack a QR code? How do QR codes work? What are the parts of a QR code? A standard QR code is identifiable based on six components: Quiet Zone - This is the empty white border around the outside of a QR code.
Without this border, a QR reader will not be able to determine what is and is not contained within the QR code due to interference from outside elements. Finder pattern - QR codes usually contain three black squares in the bottom left, top left, and top right corners. These squares tell a QR reader that it is looking at a QR code and where the outside boundaries of the code lie. Alignment pattern - This is another smaller square contained somewhere near the bottom right corner.
It ensures that the QR code can be read, even if it is skewed or at an angle. Timing pattern - This is an L-shaped line that runs between the three squares in the finder pattern. The timing pattern helps the reader identify individual squares within the whole code and makes it possible for a damaged QR code to be read. Version information - This is a small field of information contained near the top—right finder pattern cell.
Data cells - The rest of the QR code communicates the actual information, i. Numeric mode - This is for decimal digits 0 through 9. Numeric mode is the most effective storage mode, with up to 7, characters available. It allows up to 4, characters to be stored. Byte mode- This is for characters from the ISO——1 character set. It allows 2, characters to be stored.
Kanji mode - This is for double—byte characters from the Shift JIS character set and used to encode characters in Japanese. This is the original mode, first developed by Denso Wave.
However, it has since become the least effective, with only 1, characters available for storage. However, some newer QR code readers will not be able to read this character set. There are two additional modes which are modifications of the other types: Structured Append mode - This encodes data across multiple QR codes, allowing up to 16 QR codes to be read simultaneously. What are the different styles of QR code? QR code use examples QR codes are used in numerous contexts — for example: QR codes in sales and marketing Many advertisers use QR codes in their campaigns because it provides a faster and more intuitive way to direct people to websites than by entering URLs manually.
QR codes for coronavirus tracing The coronavirus pandemic has supercharged the use of QR codes. QR codes on product packaging You may also find QR codes on the packaging for some of your favorite products. QR codes in industry QR codes were initially invented to help track parts in vehicle manufacturing, and they are still used throughout the manufacturing industry. QR codes in postal services Postal services around the world also use them.

Featured Articles What is a digital footprint? In the early s, barcode scanning was becoming increasingly laborious. Each barcode could hold just 20 characters of data, so it often took multiple barcodes on a box to convey what was inside. When a Japanese engineer by the name of Hara Masahiro — who made barcode scanners for a living — learnt of the problem, he set about solving it. Together with his team, Hara developed a two-dimensional barcode in the shape of a square, tackling the issue of limited data capacity.
However, when these new barcodes were printed with other forms of text next to them, scanning machines could not pick them up. This rendered the square barcodes impractical. This impasse was overcome one day when Hara, looking out of the subway window on the way to work, noticed that skyscrapers stood out distinctively from the rest of the landscape. He began searching for ways to distinguish the square barcodes from text.
Finally, he landed on the solution of embedding three small squares with a specific ratio of black-to-white areas at the corners of the new barcode, enabling scanners to recognise it instantaneously.
QR Codes are anchored by squares in the corner. Now you know what they are for! Another issue that Hara mulled over was whether the new barcode could still be read if it was obscured by smudges or otherwise damaged.
Again, he gleaned inspiration from his surroundings, this time while playing Go the japanese board game, not Pokemon Go during lunch. Although players were supposed to place their pieces on the intersections of the grid board, he noticed that you could still figure out where a piece is supposed to be even if its placement is slightly off.
