QR Code Payment – How It Works and Why It’s Popular

What is QR Code Payment?

QR code payment is a contactless payment method that allows customers to pay for goods and services by scanning a QR Code with their smartphone. A QR Code is a two-dimensional barcode that can store various information, such as URLs, contact details, and payment information. When scanned using a smartphone camera, the QR Code directs the user to the encoded data. In the context of payments, a QR Code contains the merchant’s account details and the transaction amount. QR code payment leverages this technology to enable customers to make payments by simply scanning the merchant’s QR Code using a mobile app. This eliminates the need for physical cash or credit/debit cards, making the payment process more efficient and hygienic. This innovative payment solution has gained immense popularity in recent years due to its speed, convenience, and security. In this article, we’ll explore how QR code payment works, its benefits, and why it’s becoming the preferred choice for businesses and consumers alike.

How Does QR Code Payment Work?

To understand how QR code for payment works, let’s break down the steps involved:

1. Merchant generates a QR code:

The merchant creates a unique QR code that contains their payment details. This can be a static QR code with fixed information or a dynamic QR code where the payment amount can be specified for each transaction.

2. Customer scans the QR code:

Using a smartphone camera or a QR code scanner app, the customer scans the QR code for payment displayed by the merchant at the point of sale or on a digital platform.

3. Payment details are extracted:

The scanning app decodes the QR code and extracts the merchant’s payment details, such as their name, account number, and transaction amount.

4. Customer confirms the payment:

The customer verifies the merchant details and the payment amount. If it’s a dynamic QR code, they may need to enter the specific amount to be paid.

5. Payment authorization:

The customer authorises the payment by entering their PIN or using biometric authentication within the payment app.

6. Instant payment processing:

The payment is processed instantly, and the specified amount is transferred from the customer’s linked bank account or mobile wallet to the merchant’s account.

7. Payment confirmation:

Both the customer and the merchant receive a payment confirmation notification and a digital receipt for the transaction.

The entire QR code payment process happens within seconds, making it a quick and convenient alternative to traditional cash or card transactions.

Here’s a visual representation of the QR code payment process:

Example of QR Code Payment

Let’s consider a real-life scenario to better understand how QR code payment works:

Imagine you’re at a café and want to pay for your coffee using QR code payment. Here’s how the process would unfold:

1. After placing your order, the cashier will present you with a QR code or printed receipt on the billing counter.

2. Open your mobile payment app, Paytm, or PhonePe, and tap the “Scan QR” option.

3. Using your smartphone camera, you scan the QR Code the merchant displays.

4. The app automatically fills in the merchant’s details and the transaction amount. You verify the information and proceed to the payment screen.

5. To authorise the payment, you enter your PIN or use biometric authentication, such as fingerprint or facial recognition.

6. Within seconds, the payment is processed, and you receive a confirmation message on your app. Simultaneously, the merchant gets a notification on their end, confirming the successful transaction.

This entire process is completed in a matter of seconds, making QR code payment a quick and hassle-free experience for both the customer and the merchant.

Types of QR Code Payments

There are two main types of QR Codes used for payments:

1. Static QR Code

A static QR Code contains fixed information and is typically used for recurring payments or fixed-price goods and services. Once generated, the information embedded in the code remains unchanged. Static QR Codes are commonly used in retail stores, where the prices of products are pre-determined.

Example scenario: A retail store selling packaged goods can display a static QR Code for each product. Customers can scan the code to pay, and the transaction amount remains the same for all purchases of that particular product.

2. Dynamic QR Code

A dynamic QR Code is generated in real-time and contains variable information specific to each transaction. The embedded data can include the transaction amount, order ID, and other relevant details. Dynamic QR Codes are more versatile and are commonly used for online payments, bill payments, and invoicing.

Example scenario: When making an online purchase, the merchant generates a unique dynamic QR Code that includes the order details and the payment amount. The customer scans this code to complete the transaction, ensuring the payment is accurately processed for that specific order.

Benefits of QR Code Payments

QR CODE PAYMENT offers numerous benefits for both businesses and consumers. Some of the key advantages include:

1. Contactless and Hygienic:

QR code payment eliminates the need for physical cash or card handling, making it a safer and more hygienic option, especially in light of the COVID-19 pandemic.

2. Speed and Convenience:

Transactions are completed within seconds by simply scanning a code, saving time and effort compared to traditional payment methods.

3. Cost-effective:

Merchants can generate QR Codes for free using various QR Code APIs and payment service providers, reducing the need for expensive point-of-sale (POS) systems.

4. Enhanced Security:

QR code payment utilises encryption and tokenisation to protect sensitive information, making it more secure than carrying physical cash or cards.

5. Increased Accessibility:

With the widespread adoption of smartphones, QR code payment enables even small businesses and street vendors to accept digital payments, promoting financial inclusion.

6. Wide Applicability:

QR codes are versatile and can be used for various purposes, including retail payments, online shopping, utility bill payments, donations, and ticketing. This flexibility makes them a preferred payment method across industries.

7. Eco-Friendly:

By reducing reliance on paper receipts, invoices, and cash, QR code payments contribute to environmental sustainability, offering a greener alternative.

Security Features of QR Code Payments

While QR code payment offers convenience, it’s crucial to ensure the security of transactions. Here are some of the key security features implemented in QR code payment systems:

Payment service providers use encryption algorithms to protect sensitive information during transmission. Additionally, tokenisation replaces actual card details with a unique digital identifier, adding an extra layer of security.

2. Two-Factor Authentication:

Most mobile payment apps require users to enter a PIN or use biometric authentication to authorise transactions, preventing unauthorised access.

3. Dynamic QR Codes:

The use of dynamic QR Codes ensures that each code is unique to a specific transaction, reducing the risk of fraudulent activities.

4. Secure Protocols:

Payment service providers adhere to industry-standard security protocols, such as SSL/TLS encryption and PCI-DSS compliance, to safeguard user data.

These security features provide customers and merchants with peace of mind, knowing that their transactions are protected against potential threats.
