What is QR Code: Uses, Functions, History and Security Measures 2024

What is a QR Code?

Intro about QR codes

Quick Response or QR codes are a type of matrix barcode invented in Japan. These barcodes are machine-readable optical labels containing information about the item to which they are attached.

During its inception, the automotive industry heavily utilized QR codes to track parts. However, with the constant developments in smartphone technology, QR codes have found numerous uses in many other sectors. Issues like web page redirection, storing personal information, or initiating a call or text message to a specific number can be resolved just by scanning these codes on your smartphone.

QR codes are a perfect example of how technology can simplify tasks and make our routine activities more convenient. They are accessible, easy to use, and hold a significant amount of data, making them popular among marketers.

Even with their ubiquity, the question 'What is a QR code' is still common among many people. So, let's delve deeper into the history and functioning of QR codes.

History of QR codes

The origin of QR codes dates back to 1994 when Denso Wave, a subsidiary of Toyota, invented them. They needed a system to keep track of vehicles during the manufacturing process, and traditional barcodes were not fulfilling their requirements. Why? Because barcodes could only hold 20 alphanumeric characters, whereas Denso Wave needed a system that could handle more information in less space.

And so, the QR code was born. This new system could handle up to 7,000 numeric characters in less space than traditional barcodes. Moreover, its fast readability and greater storage capacity brought the system immense popularity.

From there, QR codes transcended from the manufacturing industry and found their way into other sectors like retail, marketing, education, and more, due to their ability to connect the physical world to the digital one almost instantaneously.

In the next sections, we will be delving deeper into QR code technology, its types, uses, security aspects, and more. So, stick around as we unlock the mystery around QR codes!

QR Code Technology

qr code technology

Let's dive into the captivating technology area of QR codes. QR codes are built on the foundation of basic yet effective technology inspired by the inadequacy of conventional barcodes. Understanding how QR codes work and the science behind them could help you harness their potential better.

How do QR codes work?

QR codes work on the principle of scanning and reading. They consist of black squares arranged on a white background. A smartphone camera can scan these squares, convert the data, and access encoded information immediately.

Each QR code uses both horizontal and vertical positioning to store data, unlike traditional barcodes, which rely on horizontal data storage only. Once the camera scans a QR code, it interprets the arrangement and sizes of the black and white squares and translates it into binary code. This binary code is then converted into usable data (like text or a URL) by the smartphone.

QR codes vs Bar codes data capacity

As previously mentioned, one of the critical reasons why QR codes were invented was to overcome the limitations of barcodes in terms of their data capacity. So, how do QR codes and barcodes differ in this aspect?

While traditional barcodes can store up to 20 alphanumeric characters, a QR code can store a significantly higher amount of data. A single QR code can theorectically hold up to 7089 numeric characters or 4296 alphanumeric characters. This means QR codes can contain complete sentences or paragraphs, URLs, locations, email addresses, phone numbers - practically, any information you wish to communicate to your scanner. Meanwhile, a barcode can only hold shorter pieces of information like price or product ID.

This data storage capacity is a result of how QR codes store data. QR codes store information both horizontally and vertically, forming a matrix. On the other hand, barcodes gather data one-dimensionally, only in horizontal form.

Anatomy of a QR Code

The QR code comprises several main elements:

  • QR code version - QR codes are made up of an 8x8 pixel module where the 4 outermost layers are: Eye Finder (7x7), Eye Separator (5x5), and Eye Alignment (3x3).
  • Quiet zone - This is a buffer space surrounding the QR code to ensure its readability. This allows the scanner to correctly locate the edges of the QR code.
  • Positioning and alignment markings - These ensure the QR code can be scanned and read from any angle. Including multiple alignment markings ensures larger QR codes can be read successfully.
  • Timing and version information - These determine the size and version of the QR code.
  • Data cells - The black and white squares carry the data that a smartphone can read.
  • Error correction - This feature counters possible data loss due to damage or dirt on the QR code. Depending on the level of error correction applied, a QR code can maintain complete data, even if partially damaged.

Encoding in QR codes and Decoding example

Each QR code consists of a unique pattern of black and white squares that represent encoded data. This data can include alphanumeric text, numbers, or binary information. The square module and the corners of the QR code - known as 'positioning marks' - help a QR reader locate, align, and decode the QR code.

When a smartphone scans a QR code, the QR code reader analyzes the patterns of black and white modules. The reader then converts this optical data into a binary sequence, which is further converted into the original data using an algorithm.

For example, let's look at a simple case - a QR code that directs to a website with the URL 'www.example.com'. This URL will be first converted into a binary sequence, which will translate into a pattern of black and white squares in the QR code.

Upon scanning this QR code, the camera on your smartphone captures this pattern, translates it back into the binary sequence, and further reconverts it into 'www.example.com'. Thereafter, your smartphone automatically opens up a browser to direct you to this website.

In the same context, dynamic QR codes can direct you to a different URL each time you scan them. With such examples, it's easy to understand how powerful a QR code can be - essentially acting as a direct channel between a physical object and a digital piece of information.

In the next sections, we will be discussing the different types of QR Codes and their specific uses that cater to varied requirements. We'll also touch base on QR codes' practical uses in various industries, how you can create one, and their safety concerns. So, stay tuned as we continue unfolding the mystery behind QR codes!

Types of QR codes

As we've seen in previous sections, QR codes are versatile and adaptable tools for bridging the digital and physical worlds. They come in various types, each designed to meet specific needs and capacities. Here, we will illuminate the different types of QR codes and how they cater to various requirements. We have another blog post about comparing static and dynamic qr codes.

Static QR Code

Static QR codes are the simplest and most commonly used type. They contain permanent information that is encoded at the time of creation and cannot be edited later. The data within a static QR code could be anything from a website URL, phone number, or plain text. As these QR codes cannot be changed once created, they are often used for information that remains constant, like home addresses or business cards.

The primary advantage of static QR codes is their simplicity and ease of use. However, they lack certain capabilities, like tracking scanning data or changing the content dynamically.

Dynamic QR Code

Dynamic QR codes differ from static ones in that their stored data can be changed or updated without changing the QR code itself. This feature is a boon for businesses who want to keep their QR content fresh or need to redirect a QR code to an updated web page. Unlike static QR codes, you can track and analyze scanning data, such as the number of scans and the geographical location of scans, with dynamic QR codes.

Because of these features, dynamic QR codes are the preferred choice for marketing and sales campaigns. They allow businesses to track campaign engagement, understand customer behavior, and quickly update campaign content as needed.

Model 1

Before QR codes became prevalent, we had what were called Model 1 QR codes. They were the first QR codes ever created and are now considered the prototype of modern-day QR codes. These QR codes feature a maximum of 14 rows and 14 columns. Despite their history, Model 1 QR codes are not commonly used today and are interpreted by very few scanners.

Micro QR Code

A Micro QR code is a smaller version of a regular QR code. It's used where space is limited and includes a smaller number of pixels or modules. Unlike standard QR codes which have placement markings in 3 corners, Micro QR codes have them in just one corner. This makes them compact and suitable for small items such as business cards or product tags.

IQR Code

An IQR code, or Intelligent QR code, is a proprietary version of QR codes with the added advantage of customizable shapes. Unlike traditional QR codes, which have a square format, IQR codes come in rectangular forms as well. This can be beneficial for precise applications where space might be restricted or uniquely shaped.

Secure QR Code

Secure QR codes help prevent tampering and unauthorized reading of the QR code content. These QR codes employ encryption to protect data and can only be accessed with the correct decryption key. Secure QR codes are used for sensitive applications such as confidential documents, tickets for events, or verification processes. In a world where privacy is paramount, the use of secure QR codes is on the rise.

Frame QR

Frame QR codes, sometimes referred to as logo QR codes, have a graphical frame surrounding the actual code. This frame can include instructions like "Scan me," a company logo, or other design elements. It not only makes the QR code visually appealing but also prompts users to take action to scan the QR code. In marketing campaigns, Frame QR codes set businesses apart and make them more attractive to prospective customers.


High Capacity Colored 2-Dimensional (HCC2D) codes are an advanced version of QR codes, capable of storing and transmitting more data than traditional black-and-white QR codes. An HCC2D code can consist of multiple colors, and each color adds another level of data storage. Although not commonly used due to incompatibility with many scanners, HCC2D codes are notable for their inventive approach to expanding the data capacity of QR codes.

All these different types of QR codes serve a particular purpose and cater to various requirements. Understanding these types will help you select the right QR code for your needs.

Next, we will explore a wide range of real-world applications of QR codes, ranging from sales and marketing to industry and education. We'll also look at some unique uses that might surprise you, such as QR codes used for coronavirus tracing and even in funerary contexts!

QR Code Security

As we become more accustomed to using QR codes in our daily lives, it's essential to address the elephant in the room - security. How safe are QR codes? Can QR codes be hacked or manipulated? And more importantly, how can we secure our QR codes? We aim to answer these pressing queries in this section.

QR codes and safety

To start with, it's noteworthy that QR codes in themselves do not pose any inherent security risks. The QR code is merely a tool to direct users to an online destination or reveal certain data. Herein lies the key: the security risk arises not from the QR code itself, but from where it directs the user.

Consider this scenario: QR codes that direct users to a malicious website where they are prompted to enter personal data, or that trigger a download for harmful software, pose a potential security threat. To put it simply, the user must exercise the same caution they would when clicking on a link received via email or encountered on the internet.

The root of the security concern lies not in the technology of QR codes, but in their usage and the intentions of the one generating the code.

Are QR codes safe?

QR codes are, by design, as safe as conventional URLs and have the same vulnerabilities to hacking. That is, just as a URL can lead to a safe or an unsafe site, a QR code can do the same. The safety of a QR code depends on the destination it's attached to.

So, while QR codes themselves are safe, the destination they link users to might not be. Therefore, security precautions should be taken while scanning a QR code, especially if you do not trust its source.

Can someone hack a QR code?

In terms of "hacking," it's important to understand that QR codes are not inherently hackable. The information they contain is static and doesn't change once the QR code has been generated. However, a malicious entity might create a QR code that links to a harmful location or change a legitimate QR code to redirect to a malicious site.

In one common attack method, called QR code substitution, criminals replace legitimate QR codes with tampered ones that direct the user to a harmful site. The identical appearance of all QR codes makes it challenging for users to differentiate between legitimate and tampered codes.

Another method, termed QR phishing or "QRishing," involves creating a QR code that leads to a phishing website. Here, the user might be asked to input sensitive information, like their banking details or login credentials, under the pretense of a plausible service.

As a rule of thumb, if you're unsure about the legitimacy of a QR code, it's better not to scan it.

How can I increase QR code security?

Given the potential misuse of QR codes, you might be wondering - what can we do to make QR code scanning safer? Here are some tips to increase QR code security:

Use Secure QR Code Reader: Some QR code readers can check the safety of the website before opening it. These secure readers can warn users if a website associated with a QR code has harmful content or is known to be suspicious.

Verify Source: If the QR code has been cut from its original context or received from an unknown source, it's safer not to scan the QR code.

Use Dynamic QR Codes: Using a dynamic QR code allows you to change the URL associated with your QR code. If your website's security gets compromised, you can change the QR code’s destination to a secure site.

Look for Tampering: QR code tampering or replacement is common. If a QR code appears to be stuck over something else or doesn't fit in well with the surroundings, it's safer to avoid scanning it.

Use Anti-Malware Software: To protect from malicious software downloads, always keep your anti-malware software updated on your devices.

QR Code Scams

Just like email phishing scams, QR code scams have become increasingly prevalent with the rising use of these codes. Scammers embed QR codes with links to fraudulent websites, phishing forms, or malicious app downloads.

Unsuspecting users might scan such QR codes and land on a convincing fraudulent site mimicking a legitimate site. The user might then reveal vital personal or financial information, which can lead to identity theft or financial fraud.

In conclusion, QR codes are as safe as the hands they are in. The information embedded in QR codes is not dangerous in itself, but it can be used maliciously. As ever, user vigilance and caution are the best defenses against cyber threats.

The world of QR codes is captivating and vast. Stay tuned as together we continue to explore the potentials of this technology, and in the next section, we will venture into the exciting realm of QR codes' future as we march towards an increasingly digital world.
