The global expansion of mobile and smartphone technology has notably influenced the rise of mobile services, particularly in the realm of banking.

The onset of the pandemic prompted both merchants and consumers to opt for contactless payment methods, resulting in a surge in online payments surpassing conventional credit and debit card transactions.

Quick Response Code Payment (QR Payment) stands out as a notably popular medium, primarily due to its user-friendly nature and utilization of smartphones for transaction facilitation. This payment method offers unparalleled convenience and advantages compared to other widely available payment options.

In this blog, discover more about QR code payments and how they have become increasingly significant for businesses in today's landscape.

What are QR payments?  

QR code payments are a secure and contactless payment method where transactions are completed by scanning a QR code using a mobile app. Quick Response (QR) codes, a type of matrix barcode, enable safe and convenient exchanges between customers and merchants, easily scanned by smartphone cameras. 

These QR codes, being two-dimensional matrix codes, possess the ability to be read from different directions, horizontally or vertically, enhancing their versatility in scanning. Users initiate payment confirmation by scanning these QR codes through a mobile app or payment platform, ensuring a smooth and secure payment process.

How do QR payments work? 

QR code technology offers a convenient way to facilitate transactions. When a customer initiates a QR payment, a process is followed (described in the image below). 


Understand the QR code payments process in more detail:

  • The customer uses their smartphone's camera to scan the QR code presented by the vendor. This code typically contains payment information, such as the recipient's account details and the payment amount.
  • Upon scanning the QR code, the smartphone triggers a notification or opens a link associated with the code. This notification directs the customer to a payment page or dedicated app displaying the transaction details.
  • On the payment page or app, the customer may need to confirm the payment amount and enter any necessary details, such as a PIN, or selecting a preferred payment method (like a linked bank account or digital wallet).
  • After confirming the transaction details, the customer submits the payment. This action authorizes the transfer of funds from the customer's account to the vendor's account.
  • Once the payment is processed, the vendor sends a digital receipt or confirmation to the customer's smartphone. This receipt serves as proof of the completed transaction.

What are the advantages of using QR payment systems? 

QR code payment systems offer a seamless, secure, and adaptable way of making and receiving payments, catering to the evolving needs of businesses and consumers. Some of the QR payment benefits are:

1. Ease of use

Users simply need a smartphone equipped with a camera and a QR code scanner app, which is often readily available. The simplicity lies in the scanning action; instead of manually entering lengthy payment details, a quick scan suffices, reducing errors and time spent at the point of sale. 

This straightforward process contributes significantly to the ease of adoption for individuals less tech-savvy or those looking for a hassle-free payment method.

2. Wide acceptance

With the widespread use of smartphones, QR codes have gained immense traction. Virtually everyone carries a device capable of scanning QR codes, making it convenient for both merchants and customers.

As people become more accustomed to using their smartphones for various tasks, performing mobile QR payments has become a familiar and intuitive action.

3. Highly secured

QR payment systems often employ robust encryption methods to secure the transaction data embedded within the QR code. By encrypting sensitive information, QR payments significantly reduce the risk of interception or data breaches during the transaction process. 

Moreover, they limit the exposure of personal details, minimizing the potential for fraud or identity theft. 

Many QR payment systems also integrate additional security layers such as biometric authentication or multifactor authentication, elevating the overall security posture and instilling confidence among users regarding the safety of their transactions.

4. Faster payment speed

QR payment systems offer a remarkable speed advantage compared to traditional payment methods. The swiftness stems from the streamlined nature of QR codes, which encode payment information into a scannable format. 

Rather than manually entering lengthy details or waiting for card authorizations, a quick scan enables near-instantaneous verification and processing. This accelerated payment speed is particularly advantageous in bustling retail environments, reducing queue times and enhancing overall customer satisfaction. 

5. Capability of integrating loyalty programs

By embedding loyalty information into QR codes, these systems enable users to not only make payments but also earn rewards or redeem loyalty points in a single transaction. This integration streamlines the customer experience, eliminating the need for separate cards or identifiers for loyalty programs. 

Furthermore, for merchants, this integrated approach provides valuable insights into consumer behavior and purchasing patterns, enabling them to tailor personalized offers and incentives, thereby enhancing customer retention and loyalty.

6. Increase customer loyalty

Providing a payment method that aligns with modern consumer habits demonstrates a business's commitment to staying current and meeting customer preferences, which in turn fosters loyalty.

Customers appreciate the convenience of using QR payments. The seamless, quick, and hassle-free transactions create a positive experience, fostering a sense of loyalty toward businesses that offer this payment method.

Businesses can gather data from QR transactions, enabling them to understand customer preferences better. This data can be leveraged to offer personalized promotions or recommendations, enhancing the customer experience.

7. Trackable QR code scans

Another advantage of QR payment systems lies in their trackability, offering businesses valuable insights into consumer behavior and transaction patterns. This tracking ability empowers businesses to refine their marketing strategies, optimize inventory management, and personalize customer interactions. 

Also, the trackability of QR code scans aids in fraud prevention and security measures, allowing businesses to monitor and identify any suspicious or unauthorized activities swiftly. 

How to generate QR payment codes? 

Generating QR payment codes involves a series of steps, typically initiated through a payment service provider. Here’s a breakdown of the process:

1. Choose a payment service provider

Select a payment service provider that supports QR code generation for transactions. These providers often offer various features tailored to businesses' specific needs, such as integration options, security measures, and compatibility with different payment methods.

2. Create a merchant account

Register and create a merchant account with the chosen payment service provider. This account serves as the hub for managing transactions, accessing payment tools, and generating QR codes. During the registration process, you'll likely need to provide business details, and banking information, and verify your identity to ensure compliance with regulations.

3. Access the QR code generation feature

Once your merchant account is set up, navigate to the provider’s dashboard or payment tools section. Look for the QR code generation feature within the dashboard or associated tools. This feature allows you to create QR codes tailored to your business needs, such as specifying transaction amounts, item details, or other relevant payment information.

For example, with PayBy, you can generate a QR code to accept open or fixed payments from customers. 

4. Enter payment details

Start by inputting the specific payment details into the QR code generator. These details typically include information such as the transaction amount, currency, recipient details (merchant or individual), and any additional necessary information for the transaction to be completed accurately. This step ensures that the QR code encapsulates all the essential data required to process the payment.

5. Generate the QR code

Once the payment details are entered, the QR code generation process begins. The system processes the information and converts it into a scannable QR code format. The generated QR code is unique to the transaction and contains encrypted data representing the payment details.

6. Test the QR code

Before deploying the QR code for public use, it's crucial to test its functionality and accuracy. Scan the QR code using a compatible QR code reader or the designated testing tools provided by the payment service provider. This step ensures that the code accurately represents the intended payment details and that it can be successfully scanned and processed without errors.

7. Deploy the QR code

After confirming the functionality and accuracy of the QR code, it's ready for deployment. Integrate the QR code into various platforms or mediums where payments are accepted. This could include websites, invoices, mobile apps, or (most often) in physical storefronts. Ensuring visibility and accessibility of the QR code to customers or users is essential for facilitating smooth and convenient transactions.

Are QR code payments safe to use? 

QR code payments indeed offer several safety measures but also present potential vulnerabilities that users and businesses need to be aware of to ensure a secure transaction environment.

Safety measures in QR code payments

Credit and debit card checks

QR code payments often link to credit or debit cards processed through reputable networks like Visa or Mastercard. Transactions undergo the same rigorous security checks and encryption protocols as traditional card payments, ensuring a secure and reliable transaction network.

Local payment methods

Customers benefit from the flexibility to choose their preferred local payment method when using QR codes. This familiarity with a trusted payment system instills confidence and trust in the transaction process, promoting a sense of security for users.

Tokenization and encryption

QR codes use tokenization and encryption, ensuring that sensitive customer data isn’t stored within the code itself. By removing the need for personal information within the code, QR payments substantially minimize the risk of fraud related to data breaches.

Potential vulnerabilities

Malicious code embedding

Attackers might embed malicious URLs within QR codes, leading to various threats. These codes can direct users to phishing sites, extract data from mobile devices, or initiate malicious software downloads. This underscores the importance of scanning QR codes from trusted sources and being vigilant about where and how codes are obtained.

User awareness

While QR codes seem innocuous to most users, they can trigger actions beyond opening websites, including adding contacts or composing emails. This lack of awareness about QR code functionalities can be exploited by attackers to initiate unexpected actions on users’ devices.

Device vulnerabilities

Mobile devices, where QR codes are predominantly used, are generally considered less secure than computers or laptops. Consequently, they are more susceptible to potential security threats, making it crucial for users to maintain updated security measures on their devices.

Data collection by QR codes

QR code-generating software typically doesn’t collect personally identifiable information. However, it gathers data about the code's usage, including the number of scans, timing, and the device’s operating system. This information aids creators in understanding user behavior but doesn’t involve personal identification.
