A short review of QR code origin
Masahiro Hara was a Denso Wave employee who invented the QR Code in 1994 to track car parts during manufacturing. But this story is only part of it. This hidden story explains the rise in QR Codes in more detail.
Every street witnessed a rise in supermarkets in 1960 when Japan entered a period of high economic growth. The majority of supermarkets sold food and clothing. This economic growth led to high-frequency buying activities that put high physical demands on cashiers.
Shortly after that, Barcodes were introduced, saving cashiers the day. They could store price information in cash registers by scanning the items.
However, Barcodes were limited to only 20 alphanumeric characters, making it difficult to store large quantities of item details. At the time, Denso Wave was developing barcodes; people reached out to Denso Wave to improve barcode information storage.
Masahiro Hara, at a small Denso Wave developer group, began to develop a 2D Code-the QR Code – that would allow users to store large amounts of data.
Scanning the QR Code was their biggest challenge. However, they eventually solved it by understanding code patterns and positioning.
QR Codes have become so popular that they are currently used in many other countries. In addition, many industries and countries have seen an increase in QR Code adoption due to the increased use of digital technologies.
360 Research reports have confirmed this finding and stated that the Global QR Code Market is projected to grow from $916.7 Million in 2020 to $1,268.1M in 2026.
Let’s now learn more about QR Codes. This guide will provide information about the basics of QR Code technology.
What are QR codes?
QR codes, also called Quick Response codes, can identify two-dimensional barcodes. Used to store data. They are most commonly used to store website URLs and can easily be scanned using a smartphone camera. QR codes are increasingly in demand as they become more popular, providing a convenient way to access digital content with a simple scan. They also store other types of information, such as contact details, text messages, locations, and geofences. QR codes can be found on products, advertisements, and websites. They are a valuable tool for businesses as they provide a quick and easy way for customers to access information.
The Ultimate Guide to QR Codes in 2023
What is the distinction between a QR Code and a Barcode?
Barcode is a one-dimensional data holder that has limited data storage capabilities. Here are some tips that make QR codes the clear winner.
QR codes make it easier to identify unique individuals.
Imagine that similar items are bought multiple times. A barcode scanner will be able to recognize numerous transactions. However, the barcode number on identical items will not have the same patterns, so it can not understand the transaction as multiple purchases. The barcode scanner won’t recognize whether it is a repeat or one-off purchase.
Let’s say you have an IT asset like a monitor, mouse, or CPU in your office. How can you distinguish between CPUs made by the same manufacturer? Each CPU with a similar design will have a unique QR code tag. Any smartphone can quickly scan this QR Code tag. As a result, IT professionals can access asset data at lower costs.
QR codes allow for easy scanning and immediate access to stored information.
To read encoded barcode information, one needs a professional scanner. The average barcode scanner cost is between $30 and $100. This barcode scanner requires additional business investment.
However, anyone can scan a QR code with their smartphone from any direction.
QR Codes provide excellent data storage capabilities.
A barcode can store 1,556 bytes. A QR Code can house up to 7,089 numeric characters and 4,296 alphanumeric ones. Two thousand nine hundred fifty-three (2953) bytes can store 1,817 kanji characters.
Structure of the QR Code: Explained
Most QR codes used in commercial spaces are usually black dots on a white background. However, this is only sometimes true. We will discuss this in a later section. Now let us focus on the components of a QR Code.
- Position Markers
- These are the squares that surround the QR Code’s three corners. They allow scanners to read QR Codes and accurately identify their orientation quickly.
- Alignment Markers
- These are smaller than position markers. A QR Code can be scanned from all angles by an alignment marker.
- Timing Patterns
- These are the lines that connect position markers. They allow scanners to determine the size of the data pattern.
- Version Number
- These are placed around position markers and give information about the version of the scanned QR code. For example, the number of rows and columns a QR code would have is called a version. It can range from 1 to 40.
- Version one (1) has 21 rows and 21 columns.
- Similarly, version 40 has 177 rows and 177 columns.
- The higher the version number, the higher the QR Code capacity.
- Format Information
- These are located around position markers. They contain information about error tolerance, mask pattern details, and other helpful information for smooth scanning.
- Module Data
- They are the same as the rest of the Code and contain actual data.
- Quiet Zone
- It is made up of space and helps a scanner find position markers.
QR codes were only available in black and white.
In the 90s, the QR Code trend was dominated by black pixels on a white background. Then, businesses began to switch to colorful QR Codes due to increased creativity and branding.
They can be found on identification cards, inventory cards, and transport cards.
There are four main QR Code formats.
Four major QR Code versions are used widely in the market. These versions are used to determine the way data is stored in QR Codes. These versions are also called input modes.
Version information is used to identify each QR Code mode.
Additional Modes These modes are modified versions of other QR Code modes.
What does a QR Code do? How can it store information, and what happens when it is scanned?
QR Code patterns are binary codes that can be interpreted to reveal encoded data information.
A standard QR Code scanner scans the three large areas around the QR Code borders to decode the internal information.
The QR Code scanner breaks down the QR Code patterns and assigns a value for each grid. The scanner then groups all grids into a larger pattern that can be used for data interpretation.
Are QR codes reliable?
Because they use Reed-Solomon error compensation for processing, QR codes are precise. This error correction ensures that the QR scanner interprets the QR Code image correctly.
Reed-Solomon offers four levels of error correction:
Be aware that QR Code blocks, also known as codewords, are used to correct Reed-Solomon errors.
- L (Low)
- Nearly 7% of codewords are possible to be restored at this level.
- M (Medium)
- Nearly 15% of codewords are possible to be restored at this level.
- Q (Qaurtile)
- Nearly 25% of codewords are possible to be restored at this level.
- H (High)
- Nearly 30% of codewords are possible to be restored at this level.
Noting that QR Code storage capacities decrease with higher error correction levels is essential. This is because the QR Code version and the error correction level will affect the data-to-error ratio for a QR Code block.
The top 4 QR Code myths
QR Codes are a standard method of identifying and contacting businesses or users. However, several misconceptions can make it difficult for many people to use them. So, let’s dispel some common myths.
- QR codes do not provide enough business capabilities.
- QR Codes are used to redirect users to legitimate websites. Most people have seen them. QR Codes can provide more than just access to coupons and map locations. They also allow users to access app downloading links. Audio, social media pages, business cards, pdfs, and forms. Landing pages, phone numbers, and other information.
- Scanning a QR Code does not make you secure.
- Many people believe QR codes need to be more secure. It is false. It all depends on QR Code usage and not scanning random QR Codes.
- Malicious activity is usually caused by a URL that isn’t secure. This can allow users to steal their credentials and track their location illegally, among other things. The QR Code is unhackable.
- QR codes can be easily damaged.
- QR Codes are often thought to be susceptible to easy damage. However, as mentioned earlier, QR Codes are not easily damaged due to the Reed Solomon error correction.
- Visual recognition will scan QR codes.
- This is not true. Visual recognition is challenging to implement on a business website due to high costs and other technical hurdles. However, QR Codes can be deployed if they are correctly generated and follow best practices.
