A two-dimensional barcode known as a QR Code typically consists of black and white pixel patterns. They were created for identifying components by Denso Wave, a Japanese division of Toyota supplier Denso, to quicken the logistics of their auto manufacturing. With the wide usage of smartphones, it has now made its way into mobile marketing. Quick Response, abbreviated “QR,” refers to the fast access to the data buried in the Code.

A QR code is a type of barcode that a digital device can scan easily and that contains data as a string of pixels arranged in a grid with square corners.

Due to the fact that many smartphones come equipped with built-in QR readers, QR codes are often used in marketing and advertising efforts. They are also frequently used to track information about products in a supply chain. They have been crucial in recent efforts to track coronavirus exposure and restrict the virus’s growth.

What Advantages Do QR Codes Offer?

They are becoming more and more well-liked due to their adaptability. By using them, you can increase client interaction with photographs or videos, collect feedback for the improvement of your goods or services, or even advertise your company through events and discounts. With just one scan, all of these tasks can be completed!

The classic black and white square shape of a QR code is now something that we are all quite familiar with. The widespread use of QR codes is a result of the increased availability of smartphones and high-speed internet. That explains why we encounter it so frequently in advertisements, movies, and other media.

In the US alone, 11 million households will scan a QR code in 2020, according to Statista’s analysis. This figure exceeds the 9.76 million scans that were recorded in 2018.

QR Codes are utilized extensively outside of the US. Other nations in the race include France, Australia, Malaysia, Singapore, Switzerland, Thailand, Indonesia, and Canada.

Additionally, the use of QR codes increased significantly across Africa and the Middle East, going from 12% in 2017 to 18% in 2018.

What are QR codes, and what is their background?

The acronym QR stands for quick response. The QR Code is nothing but a two-dimensional code. It has a pattern of white squares with a square grid and black squares in it. Reading can be done with imaging equipment like smartphone cameras.

With the exception of the fact that it can hold more data per unit space, QR Codes and bar codes are very similar.

The QR Code was developed in the 1990s by a Japanese company called Denso Wave. Initially, production, tracking, and shipping were the key uses of QR codes in the automotive sector. However, it was gradually utilized outside the automotive industry for uses like marketing and item identification.

The QR codes’ initial years did not go as planned, according to several experts.

However, in other nations, like China, it was extremely important to the explosive expansion of QR code mobile payment services since it allowed companies to take digital payments without having to invest in expensive hardware like point-of-sale terminals.

How do they function?

The fact that QR codes may be read from both paper and screens is a key distinction between them and barcodes. Contrarily, linear barcodes can only be scanned from paper. The reason you see QR codes on applications and at online retailers is because of this.

You’ll require one of the following to scan a QR code:

  • A scanner that can read barcodes and scan QR codes.
  • A tablet computer or a smartphone with a camera.

These days, consumers may easily scan QR codes thanks to the numerous QR code scanning apps that are readily available. Simply opening the camera and pointing it at the QR code will instantly recognise it and trigger the opening of a push notification. After that, all the user needs to do is tap on it to complete the action.

Some banking and payment applications can also decode QR codes to perform payments and bank transfers.

A QR code can be scanned in a variety of ways. Below are some of its components:

Using a smartphone to scan the QR code of the recipient

The user must first open the software that will allow them to scan QR codes with their phone’s camera. After then, users must scan the barcode that is visible on specific goods, a paper bill, or at the register in a store. If the application is store-specific, various deals and loyalty points may also be applied via it.

Retailers scanning the user’s smartphone screen for QR codes

Both the sender and the recipient open their applications during this process. The recipient’s smartphone generates a distinct QR code, which the sender then scans. Finally, the sender acknowledges the payment amount and taps to finish the transaction.

Varieties of QR codes

For QR codes, there are two different classifications. Let’s examine each one in turn.

Permanent QR code

This kind of QR code contains the URL of the target website right there in the barcode. These QR codes’ text cannot be changed. These cannot be tracked, but by mentioning the URL, they can be fixed.

Once the total transaction amount is set in the retailer’s POS system during the QR code payment procedure, the user opens the payment app. The QR code payment app shows a QR code that corresponds to the user’s credit card information. The purchase is then completed when the retailer scans the QR code with a scanner.

App-to-app transactions

In many different businesses, including delivery services, in-home services, in-store retail, taxi drivers, and street sellers, static QR codes are utilized to facilitate quick and easy payments. With all of this, all a user needs to do to make payments is to scan the QR code.

Movable QR code

You can modify the dynamic QR code. It also has extra features like device-based redirection, scan analysis, password security, and access management. With dynamic QR codes, you may also learn other information, such as how many users scanned the code, what kind of device they used, where the scanner was located, etc.

Nowadays, businesses utilize dynamic QR codes frequently since they can transmit information about the business and the purchase’s price. This feature requires the user to do nothing more than accept the transaction in their application. Additionally, it implies that the sender of the QR code has greater control over the payment amount.

For the static QR code, the customer had to enter the purchase amount, which the retailer then had to meticulously check. The dynamic QR code, however, takes all of those into account and provides a superior payment experience for both consumers and merchants.

Advantages of QR codes

You can reach out to all of your potential customers thanks to the benefits of QR codes. We’ll look at a few of them now.

Quick payments

The ability to make fast payments is one of the main benefits of using QR codes. Compared to other payment methods, using QR codes is incredibly fast.

To complete the payment, a user only needs to open the QR code scanner app, scan the QR code, and confirm. The payments are completed in a short amount of time.

Superior security

Payments made with QR codes are extremely secure. The reason behind this is that a QR code is only a tool used to convey information. Any data transferred by QR codes is encrypted, making the transaction completely secure.

Simple to set up

Paying with a QR code is quite simple to set up. There isn’t much infrastructure required. All that is needed is a smartphone with a camera and a QR code, which may be printed out or stored electronically.

The use of QR codes for payments also does away with the need for a point of sale device or any other specialized equipment.

Greater dependability

Due to the zero chance of any form of error, QR code payments are a foolproof method of payment. The unique data in the black box pattern increases the trustworthiness of QR code payments.

Principal applications for QR code payments

Many businesses can make payments quickly and easily using QR codes. Let’s examine some of the main use cases for QR payments.

Fuel suppliers

Additionally, gas stations can employ QR codes to make payments simple for their customers.

Gasoline retail wallet solutions exist that enable customers to refuel their vehicles by merely entering the fuel level in the app. These programs offer a variety of payment options, including the ability to pay by scanning QR codes.

E-ticket purchase

E-ticket reservations also utilize QR codes. With only a few clicks on their phone, users of the E-ticket booking application may make reservations for a variety of tickets, including those for buses, flights, trains, cinemas, amusement parks, and more. One of the payment methods offered by these apps is QR code payment.

Tolls are paid

For quick and easy toll payments, toll booths can also use QR codes. Cashless toll payments are possible with the help of toll payment wallet apps. These apps offer a variety of cashless payment methods, such as QR code payments, RFID cards, and NFC cards.

Paying for parking

A parking payment system may use QR codes as a form of payment. A mobile application for a

parking payment solution enables its user to look for and reserve a parking place. After reserving a parking spot, the user can pay by just scanning the parking garage’s QR code.

Street sellers who only sell a small selection of goods frequently employ QR codes. For each of their products, they only print a QR code with the product’s name, price, and description. A parking payment solution allows its user to look for and reserve his parking space through a mobile application. To purchase any item, the user must scan the QR code and confirm to make the purchase.

After reserving a parking spot, the user can pay by just scanning the parking garage’s QR code.

Street hawkers

Street sellers with a limited selection of goods frequently employ QR codes. For each of their products, they only print a QR code with the product’s name, price, and description. The user must scan the QR code and authorize payment in order to purchase any item.


QR codes are also used for payments by small businesses that sell a limited selection of goods. Here, the merchant creates both the QR code and the invoice for a specific amount. The QR code is then shown on the smartphone’s screen by the user.

The consumer must use their mobile wallet application to scan the merchant’s generated QR code in order to complete the transaction.

SMEs (Small and Medium-Sized Enterprises) The merchant prints QR codes for each of his vendors in this system, indicating the location of the cash register and other information. The customer must scan the vendor’s QR code to complete the transaction. The merchant then uses the cash register to send the receipt to the customer’s smartphone. The consumer then approves the payment.

However, as the article points out, QR codes also have a number of drawbacks. It will be interesting to see how this technology changes to keep up with the ever evolving technology landscape. If it will continue to develop or if it will vanish forever, only time will tell.

Simple text, URL, SMS, or vCard contact information entry is required. As you type, a QR code will be produced automatically. Simply select “Download” to obtain the generated QR code, and after that (the image is available as EPS or SVG vector graphic, as well as high-resolution PNG, GIF or JPEG raster graphics format). Simply look at the code provided by the “Embed” button to see how you may use the QR code directly on your own website. Of course, you can add and utilize the QR graphic for free on flyers, posters, business cards, and other items.

Of course, you are free to include and utilize the QR graphic on flyers, posters, business cards, and other materials (including commercial use).

The best method for connecting real-world products with the Internet is through the use of QR codes. Because QR codes make it so simple to send a web link to a mobile device, they drastically lower the barrier to using a smart phone to access a website. However, you may also deal with various types of text and information, like marketing messages, phone numbers, and even full business cards in vCard format. Simply encode them using our QR code generator to send the information to mobile devices quickly.

Modify your QR code upon printing.

You can utilize dynamic QR codes thanks to our QR-Server software for managing QR codes. Their main selling point is the ability to update the stored QR code destination address (URL) whenever you want, even after your marketing materials have been produced, for example. You can at any time change your advertising campaigns or fix mistakes (for example if a wrong web address was used).

Important Information: Due to technical restrictions, it is not feasible to transform static QR codes into dynamic QR codes before printing.

Print-quality QR codes with high resolution

The 2D barcodes employed by the QR code (a subset of barcodes that the QR code belongs to) are comparable to the ubiquitous, one-dimensional bar codes found, for instance, on grocery store goods packaging. However, QR images have a significantly greater capacity for data storage; they can fit over 3000 characters into a relatively compact area. A QR generator must encode the data in accordance with ISO/IEC 18004:2006 in order to make one.

Technically equivalent 2D codes were displaced from the market by the QR code, which has a high data density when compared to simple barcodes, Denso Wave’s licensing policy, and the widespread availability of reading software.

Mobile marketing is where QR codes are most frequently used. Because practically every smartphone with a camera can read QR codes (including the iPhone, Google Android, Blackberry, and Symbian), QR codes are used to connect offline material like paper and websites. Instead of inputting lengthy, uncomfortable site addresses, the user only needs to scan the code.

However, the primary use of these codes for offline use is to import vCards with business contacts and addresses, initiate phone calls, or send text messages (see also “Overview of the numerous QR code kinds and capabilities”). Particularly, QR code business cards are ideal for enabling others to easily and accurately import your contact information. Put a vCard QR code on your business card by printing one.

QR code with a brand’s or image

There is a complex error-correcting method built into the QR code standard (Reed–Solomon error correction).

As a result, some QR code components can be styled. For instance, our generator allows you to alter the background and foreground colors of a code, and you can also insert a logo, for instance in the center of the QR image. Even though the contents of the QR code won’t be seen before scanning the code, embedding information that matches logos or icons gives the user a preview of what to expect. You are welcome to get in touch with us if you want a custom logo QR code made with colors that go with your corporate identity because we have a lot of expertise with them.

Styled and designed QR codes
