How to Scan and Pay with QR Code

18 September, 2023

In today’s fast-paced digital world, online payments have become the norm for many. While cash cannot be completely replaced, making payments via smartphones has become the preferred mode to save time. Among other digital payment modes, scanning and paying with QR codes is gaining significant traction. You may have come across these unique square patterns almost everywhere, from retail stores to restaurants and even in public transportation. But what exactly are QR codes and what is the process to scan to pay with them? Read ahead to understand.

How QR Code payments work

QR codes, short for Quick Response codes, are two-dimensional barcodes that you can scan using your smartphone. They consist of three black squares arranged on a white background. The typical alignment is small squares on the upper and lower left corners and another square on the upper right corner. The rest of the grid involves an arrangement of pixels.

QR codes can store various types of information, such as website URLs, contact details, text, or payment information. Unlike linear barcodes that are read through laser barcode scanners from paper, QR codes are scannable from both paper and screens. This makes them an efficient means to accept payments. Hence, most merchants display QR codes on their point-of-sale (POS) system for processing instant payments.

You can make QR code payments by scanning the QR code on the merchant’s store via a mobile payment app like PayZapp. After successful scanning, the app decodes the information like the recipient’s name, payment amount, and additional transaction data encoded within the QR code. You will then receive a prompt to pay. After executing the operation, the app will send you a payment alert.

How to scan and pay with a QR Code

The step-by-step process to scan and pay through a QR code is explained as follows:

  1. Open a mobile payment app

    Download a mobile payment app like PayZapp from your smartphone’s app store. As an HDFC Bank customer, you can install and register on the app with your bank details to link your bank account in PayZapp. Once done, you can use it to make contactless payments via Unified Payment Interface (UPI) by scanning a QR code.

  2. Position the QR Code

    You will find an option to ‘Scan QR code to pay’ on PayZapp’s dashboard. Select the option and launch the QR code scanner. You can then position your smartphone’s camera in front of the QR code. Ensure that the entire QR code is visible within the scanning frame on the screen.

  3. Scan the QR Code

    When you position your camera to align with the QR code, the app will automatically scan the code. Once scanned, the app will process the code and display payment details.

  4. Retrieve payment information

    After successful processing, the app will decode the QR code and retrieve the payment information within seconds. It typically includes the recipient’s name and the transaction amount. In some cases, you might have to enter the amount manually.

  5. Confirm the payment

    You can review the payment information and ensure its accuracy, such as the payment amount, recipient’s name, and any additional transaction details. Once satisfied, you can confirm the payment.

  6. Authorise the transaction

    Once you select to ‘Pay’, PayZapp will prompt you to authenticate your payment. The process involves entering your UPI PIN of four or six digits. Post payment completion, the app will display a confirmation message on your screen.

  7. Verify with the merchant

    Lastly, you can check the transaction details displayed on the screen and verify the same with the merchant. Besides, both you and the merchant will receive real-time notifications confirming payment for easy processing.
