Read this ultimate guide to learn all about QR Codes

A. What is a QR Code?

A Quick Response Code is a popular type of two-dimensional barcode. It encodes alphanumeric information. To decode this, you can either use a handheld scanner or even a QR Code scanning application on your smartphone.

In fact, many smartphones such as iPhone, Xiaomi, Motorola, and Samsung now have an in-built QR Code scanning feature in their stock camera application.

A Japanese company, Denso Wave Corporation, developed Quick Response Codes in 1994. Their role was vehicle tracking and high-speed component scanning in the automobile industry.

Now that you know what is a QR Code, let’s take a look at how they work. Keep reading!

B. How do QR Codes work

If you look at a QR Code, you’ll see black-colored squares (or dots) all over it. These are called data modules. The information you add to the QR Code is stored in these data modules.

Hence, every module (black or white unit block) or a string of modules either represents data or a function.

So what scanners do is—they start reading these data modules to decode the information stored in them to show the stored data to the users.

The illustration below depicts how a QR Code scanner decodes a QR Code:

Here’s a detailed guide on how QR Codes work.

Many users have some common questions before getting started with QR Codes. And you may have them too. Let’s go through these in detail:

C. Most common QR Code FAQs

1. What does a QR Code mean?

QR stands for ‘Quick Response’. Hence, the QR Code becomes a Quick Response Code.

And the reason behind this name is pretty simple. Have you ever scanned a QR Code? You might have done it most probably. In case not, try scanning one now.

It’ll hardly take a second or two for you to do the needful and see the content in the QR Code. Quick, right?

That’s exactly the rationale behind the name. Since a QR Code gets scanned in no time (response quickly), hence, the name.

2. How many times can my QR Code be scanned?

Technically, as many times as you want.

Static QR Codes, which are permanent in nature, come with unlimited scans. Once created, they can’t be deactivated. In addition, even your QR Code generator can’t limit the number of scans on them.

However, due to their limited functionality, static QR Codes aren’t really the most sought-after.

Dynamic QR Codes, on the other hand, may or may not have unlimited scans. It totally depends on your QR Code generator. Service providers such as Scanova don’t put a limit on the scans your QR Code can get.

In addition, since the dynamic ones are both editable and trackable, they’re preferred way more than the static ones. Watch this quick video for a detailed comparison of static and dynamic QR Codes.

3. Does a QR Code work forever?

As mentioned before, a static QR Code is permanent in nature and, hence, works forever. But that is not the case with a dynamic QR Code.

For a dynamic QR Code to work, you need an ongoing subscription with your QR Code generator.

4. Who is a QR Code relevant for?

There’s no specific job role, industry, department, or use case that QR Codes are relevant for. In fact, it’s the quite opposite. QR Codes are so versatile that everyone is using them.

From ads and promotions to operations, they fit everywhere. For example, in 2022, they were used by Dunzo, an instant delivery app in India, used a QR Code to promote its app. The response was so good (and unexpected) that the app crashed due to traffic overload.

On the other hand, many logistics companies use QR Codes for inventory management. Since QR Code store way more data than barcodes and are damage-resistant, they work amazingly well.

5. Can I add a design to my QR Code?

Yes, you can add a design to your QR Code. And by that, we don’t mean that you need to hire a graphic designer. Advanced QR Code generators such as Scanova offer this capability.

This feature helps you make your QR Code visually appealing in no time. Isn’t that great?

6. What is the meaning of QR Code Security? 

QR Codes themselves are inherently secure, but their security depends on how they are used. The security risk lies in where the QR Code leads you. Malicious elements can create QR Codes that link to phishing websites designed to steal your information, malware-laden downloads, or even fake login pages. 

QR Code security is simply the process of making QR Codes secure. Let’s see how you can make your QR Codes more secure:

• Be Wary of Unknown Sources: Only scan QR Codes from trusted sources. If you see a random QR Code plastered on a streetlamp, it’s best to avoid it.
• Verify the Link Before Clicking: Many QR scanner apps allow you to see the URL encoded in the QR Code before visiting it. Double-check the link for suspicious characters or typos before clicking.
• Use a Secure QR Code Scanner: Some scanner apps offer additional security features like checking the URL against known malware databases. Consider using such apps for added peace of mind.

Scanova’s Tip: We recommend using Kaspersky’s QR Code reader, which includes built-in security to prevent suspicious behavior. It also guards against viruses and questionable URLs, ensuring a safe experience for iOS and Android users.

7. Are QR Codes secure for encoding sensitive information?

Choosing a secure option is very important when sharing sensitive information, like business documents or confidential files.  Look for service providers prioritizing data privacy and adhering to industry-recognized compliance standards like GDPR, SOC 2, and ISO 27001.

These certifications demonstrate a provider’s commitment to robust security practices, offering peace of mind when trusting them with your sensitive data.

Understanding the Certifications:

• GDPR (General Data Protection Regulation):  This is a European Union regulation that governs how personal data is collected, stored, and used.  A GDPR-compliant provider ensures your data is handled with strict controls and user privacy is respected.
• SOC 2 (System and Organization Controls):  A SOC 2-compliant provider demonstrates they have robust controls in place to safeguard customer data, including security, availability, processing integrity, confidentiality, and privacy.
• ISO 27001 (Information Security Management System): Developed by the International Organization for Standardization (ISO), ISO 27001 outlines a framework for establishing and maintaining an information security management system (ISMS). 
  An ISO 27001-compliant provider has a systematic approach to managing information security risks, ensuring your data is protected throughout its lifecycle.

8. Why does privacy compliance matter when choosing a QR code generator?

 Choosing a service provider with these certifications signifies their dedication to data security.  Here’s why it’s important:

• Reduced Risk of Data Breaches: Compliance standards minimize the likelihood of data breaches and unauthorized access to your confidential information.
• Enhanced Data Privacy: These regulations and frameworks put user privacy at the forefront, ensuring your data is handled ethically and according to strict guidelines.
• Improved Transparency: Compliance certifications demonstrate a provider’s commitment to transparency. You gain confidence knowing they take data security seriously.
• Regulatory Compliance: Depending on your industry or location, complying with data privacy regulations might be mandatory. Choosing a compliant provider helps you avoid any legal ramifications.

In short, opting for a service provider that prioritizes data security and adheres to GDPR, SOC 2, and ISO 27001 standards gives you peace of mind. You can share confidential data with the assurance that it’s protected by industry-recognized best practices.

9. How to avoid misuse of data when using QR Codes?

Prevention is better than cure. Likewise, you can avoid the misuse of information and data by following the precautions mentioned below:

• Don’t Encode Sensitive Information: Avoid embedding sensitive data like passwords or credit card details directly into QR Codes. These codes can be intercepted, and the information could fall into the wrong hands.
• Use Short URLs: QR Codes have limited data storage capacity. Using a link shortener can help, but ensure the shortening service is reputable. Scanova offers the creation of QR Codes with dynamic short URLs that are secure. Also, you can replace Scanova’s standard short URL (e.g., https://scnv.io/AbCd) with a personalized URL (e.g. https://scnv.io/cafemenu or https://qr.cafe.com/menu).
• Password Protect Encoded Data (if necessary): If you must encode sensitive information, consider using a QR Code generation tool like Scanova that allows password protection. This adds an extra layer of security, requiring a password to access the encoded data.

Scanova’s Tip: You control what information you share through QR Codes. By following these tips and practicing caution, you can leverage the convenience of QR Codes without compromising your security.

F. Types of QR Codes

Say the content you want people to see is ‘target data’. Target data could be a website, a word in Spanish, your phone number, or even an image.

Classification of QR Codes depends on how this data gets encoded. There are two categories of Quick Response Codes:

1. Static QR Code

In a static Quick Response Code:

• Target data is encoded directly into the code, just like numeric data is encoded in a barcode
• The more information is encoded the ‘denser’ the Quick Response Code will become
• Encoding is permanent, which means that the target data can never be edited
• It is not possible to track scanning activity

Static QR Code can encode the following information in a structured format:

• URL
• Vcard (contact details)
• Text
• Wifi network access details
• Pre-loaded SMS
• Email address
• Phone number
• Calendar event
• Bitcoin wallet address

2. Dynamic QR Code

A Dynamic QR Code is a better way of encoding URLs in a QR Code. This confers it greater functionality and flexibility. In a Dynamic Quick Response Code:

• Target data can only be a URL
• The target URL is not stored directly in the Quick Response Code. Instead, a short URL (usually provided by the QR Code service) is encoded which redirects to the target URL
• It is possible to edit the encoded target URL at any time without the need to reprint the square barcode
• It is possible to track the scanning activity and get analytics
• You can ‘activate’ or ‘deactivate’ the Code at any time

Note that this categorization is based on how data is stored in a Quick Response Code. Based on the type of content, there can be many categories.

The number of categories of these 2D barcodes you can create depends upon the QR Code generator that you use.

Different generators offer different categories. For example, the Scanova QR Code generator allows you to create more than 20 types of Quick Response Codes.

To decide which type of QR Code you need to create, think about what action you want your target audience to take. For example, do you want them to:

1. See a website

2. See a text-based landing page

3. Listen to an audio

4. Make a payment using Paypal

5. Watch a video

6. Download a PDF

7. Follow you on social media

Once you decide what you want users to do, finalize the type of Quick Response Code you’ll create.

G. Generating a QR Code

Before you go ahead to create a QR Code, you must be clear about two things:

1. What do you want your audience to do

2. Which QR Code generator will suit your needs the best

A simple Google search on ‘QR Code generator’ will give you pages of results.

How do you then decide which service is the best for you? Will you compare all of them one by one?

Fret not! We’ve compiled a detailed comparison chart of the best QR Code Generator.

2. Integrating QR Code API with your own system

If you have a mobile application or an information system that needs to generate these 2D barcodes, then you need a QR Code API.

It will integrate with your system and generate a Quick Response Code on demand.

3. Bulk Generation Services

Some QR Code service providers give the option of bulk generation (or batch generation).

This is helpful in case you need (say) 10,000 Quick Response Codes each with a unique ID.

You simply need to specify the data to be encoded in a spreadsheet, upload it to the bulk generator, add a design to the QR Codes (optional), and make payment.

Once your batch is ready, you can download it.

H. How to scan a QR Code

This can be done in either of the two ways mentioned below:

1. Using a QR Code scanning application on a mobile device

If you own a smartphone that has a camera, you can decode a Quick Response Code.

There are a number of QR Code scanning applications on all major app stores of iOS, Android, Windows, and Blackberry OS platforms.

Scanova’s Tip: i-nigma is one such application that works well on both iOS and Android, we highly recommend using it.

Also, as stated above, some smartphones now have inbuilt QR Code scanners. Check if your phone already has one.

2. Using a handheld or fixed optical scanner

You’ve seen scanners at the retail stores used to scan barcodes. Similarly, a handheld or fixed optical scanner can scan QR Codes.

These scanners are used when the scanning volume is higher in cases such as ticketing or mobile payments.

I. Advantages of QR Codes over barcodes

In technical terms, 2D barcodes have the following advantages over traditional barcodes:

1. Higher Capacity

A Quick Response Code can store up to 7,089 numeric characters (without spaces) or 2,953 alphanumeric characters with spaces.

Compare this with the capacity of barcodes i.e. 20 numeric characters (without spaces).

The higher capacity of QR Codes allows them to be used in various industries. From marketing, security, payments, and other solutions. Note that they can store web URLs, unlike barcodes.

2. Smaller Size

Compared to a barcode, a Quick Response Code can store more information in a smaller area of space.

This is helpful in inventory management as it is possible to print more QR Code labels in the same amount of space, saving printing costs.

For marketers also, this feature is extremely helpful as they usually have limited real estate on product packaging or promotional material.

See what should be the minimum size of your QR Code.

3. Damage Resistant

This is one of the primary reasons for QR Codes’ invention. The automobile industry used barcodes on spare parts. However, the factory environment resulted in wear and tear of the barcode.

This resulted in the barcodes being no longer scannable, causing delays and inefficiencies.

To avoid this, Denso Wave invented the QR Codes.

They can tolerate up to 30% of damage or dirt. This means—they remain scannable even if they’re up to 30% damaged.

This is possible due to a property called error correction.

Damage resistance allows personalization of QR Code design

You’ve probably noticed QR Codes with an image in the center as a logo.

It is the error correction that creates room for these 2D barcodes to be personalized. How?

To accommodate an image in the center, QR Code Generation tools introduce ‘damage’  by removing some square modules from the center of the QR Code.

The image (or the logo) can then be accommodated in the space created.

(These QR Codes were designed using Scanova)

4. 360-degree orientation

Unlike barcodes, a Quick Response Code is scannable from any angle. It has ‘eyes’ in three corners. Eyes help the scanning device determine its orientation.

This is useful as users do not have to rotate the Code (or themselves) to scan the code. Scanning here is much faster compared to barcodes.

5. Kanji Encoding

Unlike barcodes, QR Codes can encode information in JIS Level 1 and Level 2 Kanji character sets. This allows them to encode in a total of four encoding modes:

1. Numeric
2. Alphanumeric
3. Byte/binary
4. Kanji

This is to make it possible to encode single-byte languages (English) as well as double-byte languages (Japanese, Chinese, Korean).

These were the technical advantages of a Quick Response Code over a barcode.

J. Industry-wise QR Code best practices

QR Codes can be a powerful tool for various industries, but their effectiveness lies in following specific best practices. Follow these general best practices to make your QR Codes more efficient:

• Scannability: QR Codes must be easily scannable for a seamless user experience. Ensure a minimum size of 1 inch by 1 inch and high contrast with the background for clear readability. 
• Placement: It is crucial to position them in well-lit, accessible areas. A QR Code will lose its purpose if the users have difficulty scanning them. Thoroughly test the code across various devices and lighting conditions before deployment.
• User Experience:  Don’t leave users guessing! Include a clear call to action (CTA) that entices them to scan. This could be a simple “Scan for discount” or “Scan to learn more.” 
• Mobile Optimized Landing Pages: The QR Code should always lead to relevant content optimized for mobile devices. To ensure smooth scanning, use short URLs that contain less data within the code itself.

K. Emerging trends in QR Code technology

QR Codes are experiencing a resurgence, and with that comes a wave of innovation. Here are some emerging trends that are pushing the boundaries of QR Code technology:

1. Interactive QR Codes and Augmented Reality (AR)

Imagine scanning a QR Code on a product package and seeing a 3D model come to life on your phone. Interactive QR Codes, when merged with Augmented Reality (AR), are blurring the lines between the physical and digital worlds. This can be used for product demonstrations, educational overlays on historical sites, or even interactive games.

2. Blockchain Integration

Blockchain technology is being explored to enhance the trustworthiness and transparency of QR Code-based systems, especially in supply chain management and product authentication. By recording QR Code scans on a blockchain ledger, it becomes possible to trace the entire lifecycle of a product from production to consumption, ensuring authenticity and preventing counterfeiting.

3. Micro QR Codes

While traditional QR Codes require a certain amount of space to be scannable, micro QR Codes are making a miniaturization revolution.  These tiny QR Codes can be embedded on smaller objects like jewelry, business cards, or even inside pills for medication tracking.

4. Secure QR Codes with Encryption

Security is of the utmost importance, especially when dealing with sensitive information. Encrypted QR Codes are emerging as a solution. These codes add an extra layer of security by encrypting the data they contain, ensuring only authorized users can access the information upon scanning.

5. Integration with IoT Devices

QR Codes are increasingly being used to facilitate the setup and configuration of IoT devices. Instead of manually entering Wi-Fi credentials or device-specific information, users can simply scan a QR Code to establish a connection or configure settings, streamlining the onboarding process.

These are just a few of the exciting trends that are shaping the future of QR Codes. As technology continues to evolve, we can expect even more innovative applications for these versatile tools.
