The Future of QR Codes and Their Role in Modern Applications

You must have often heard the name of QR code, its full form is Quick Response Code. These are small square barcodes, which have become a part of our daily life, you can see them everywhere today, in today's time we can see it everywhere. Whether we have to access a website, pay a bill, get information about a product in a store or make its online payment. To perform all these tasks, we have to scan them on our phone, QR codes are no longer just a technological novelty; they have become an essential tool on the stage of life. But how will QR codes evolve in the future? And what will be their role in modern applications?

Today in this blog we will discuss some of these points about how QR codes are changing industries and what possible developments can happen in this field in the future. Let’s take a deeper look at these points to understand how QR codes can shape the future and what impact they can have on modern technology and business.

What Are QR Codes?

QR (Quick Response) codes are a type of two-dimensional barcode. Unlike traditional barcodes, which can only store information in one direction (horizontally), QR codes can store information both horizontally and vertically. This enhances digital security and allows storing large amounts of data such as website URLs, text, images, and even videos in a small code.

QR codes were primarily invented and designed by the Japanese company Denso Wave in 1994 to track and verify vehicle parts during manufacturing. However, it gained popularity due to its speed and ease of use (storing data quickly and providing it instantly when needed) which gave a new twist to the world of technology and with the changing times, it made its place in many other fields. Today, they are used by businesses and consumers for everything from marketing to payments. And it is very safe, easy and convenient.

The Rise of QR Codes in the Digital Age

Smartphones have played a huge role in the widespread adoption of QR codes. Smartphone cameras have become so smart these days that most phones already have an in-built option to scan QR codes, making it easier to scan these codes and quickly access the information stored in them. Today, QR codes have become an essential tool for businesses that want to connect with customers in a more interactive way. 

Here are some of the key factors that have contributed to making them more effective:

Mobile Convenience:-

Ever since the use of mobile internet increased, the use of QR codes also started increasing, because it was very difficult for people to keep typing long URLs or long data. QR codes made it easier, due to which it became very easy to access any digital content.

Contactless Technology:-

As we all know that in the year 2019, COVID-19 developed as a global pandemic of contagion, during this time we were mainly prohibited from touching any place, object or even gathering in large numbers, at this time QR codes became very popular, because this was the only way that could complete any process in a contactless manner, whether it is checking the menu in a restaurant, making a payment or checking in at an event.

Cost-effectiveness:-

Creating QR codes is quite cheap and affordable, and at the same time they can be easily added to print media, websites or digital platforms. Hence, making them an attractive option for all types of businesses and technology devices.

Current Uses of QR Codes

Today, QR codes are used across a wide range of industries and applications. Here are some common uses:

Marketing and Advertising:

Nowadays, small and large businesses are redirecting customers to their website or social media for special offers through QR codes provided on their product posters, advertisements and packaging, so that consumers can easily scan and learn more about the product.

Payments:

As you may have often seen, major financial platforms like Paypal, Venmo, Paytm and Phonepe etc. have adopted the QR code system for easy and quick online payments, which helps consumers to pay for products or services without swiping the card for every transaction.

Event Management:

QR codes are also often used to make the ticketing system of an event fast and simple. Be it a concert, sports or movie, spectators can reach their designated place quickly and on time by scanning their tickets with their smartphones.

Healthcare:

QR codes are used in healthcare to store patient records, drug information, and even vaccination certificates. This helps doctors to quickly and accurately access data related to the patient's medical history, thus QR codes are helpful in starting treatment of any disease early.

Education:

Teachers can generate QR codes to distribute online study material, class assignments or question papers to students, which students can scan and easily complete the task.

The Future of QR Codes: What’s Next?

If we look into the future, we can clearly see that QR codes can play an even bigger role in the future. Here are some ways that they can open new doors for humans in the technological world.

1. Interactive Experiences with Augmented Reality (AR)

In the future, we may be able to experience a service or product in a more immersive way. For example:-

  1. By scanning the QR code on a product, we can experience its 3D model in depth before buying that product through the AR feature.

  2. By scanning the QR code, we can get information about a particular product from a digital salesman.

  3. Being able to store all our important documents in a small and safe QR code and easily access it when needed after a special owner verification.

2. Blockchain-Enabled QR Codes

Blockchain technology is well known around the world for its digital security, as it is a series of codes that are very difficult to hack, so in the near future it may also happen that blockchain technology starts working in conjunction with QR codes and we can verify the authenticity of a particular or common product by scanning blockchain-based QR codes, track shipments or increase the security of any digital transaction. For example, when a user scans a QR code on a luxury/expensive item, they can verify its authenticity through blockchain technology, that it is not a fake product.

3. Smarter QR Codes with Embedded Data

Currently, QR codes are capable of storing only static data/fixed amount of data. Whereas, in the future, QR codes can be made capable of storing dynamic and unlimited data. For example, information can be recorded in a QR code that keeps getting updated in real time. This can be especially useful for scheduling live events, real-time promotions, or tracking inventories in real-time.

4. QR Codes in IoT Devices

As more devices are getting connected via the Internet of Things (IoT), in the future, QR codes can also be used to pair or control smart devices in the home or office with our smartphones. For example, we can easily pair a device with our smartphone by scanning its particular QR code and then control everything from the brightness of the lights to the temperature setting of the AC.

5. Sustainability and Eco-Friendly Solutions

Global warming is still a burning issue today, one of the main reasons for which is cutting trees to make paper. To maintain environmental sustainability, we need to plant trees as well as reduce their felling and QR codes can also help us extensively to reduce the need for cutting trees. For example, instead of taking paper brochures, tickets or bills (printed receipts) of the goods purchased, we can receive them digitally by scanning a QR code and this scheme should be promoted on a war footing. Because only through this scheme we can reduce the pollution emitted on a daily basis.

Challenges to Overcome

Till now we have seen how we have been using QR codes and how we can use them extensively in the future, but like everything in the world there are challenges as well which need to be solved on time, let us know:-

Security Risks:

As the use of QR codes is increasing, a concern is also emerging that is directing users to malicious websites or installing malware on their devices. Therefore, to avoid such incidents, it is important for businesses and consumers to be aware of these risks and ensure that there is some verification layer for security after scanning the QR code.

User Awareness:

Even today, there are many places and older generations in the world where people are still not fully connected to technology, in such a situation, not everyone may be able to use QR codes. Therefore, it is important to spread awareness among people about how QR codes make our daily routine tasks easier and how they can benefit us.

Scanning Limitations:

To read QR codes, we usually need a smartphone. Although, nowadays it is available with most people, but there is often a problem in scanning QR codes when the surrounding light is poor or the code is damaged from somewhere. Therefore QR codes must be displayed clearly and in an environment where they can be easily scanned.

Conclusion

Invented in 1994, QR codes were first introduced in the automotive industry as a way to verify and track spare parts, and because it was a quick and easy way to provide instant information, it was adapted to other industries and has now become a versatile technology used in industries ranging from marketing to healthcare. In the future, QR codes will evolve even further, becoming more interactive, secure and compatible with emerging technologies such as augmented reality as well as blockchain.

QR codes are a simple way to connect the physical world to the digital world, streamlining the user experience in exciting ways. Today, you scan a QR code to get a special offer, or even to pay for a coffee or bar, or to check the authenticity of a product. However, looking at these circumstances it proves that QR Codes are going to remain permanent in the world and will develop further in the future.
