The Rise of QR Codes: Changing the Face of Digital Payments

Digital payments are one of the most used form of transactions today in this tech driven world. India leads the way in cashless transactions, compared to rest of the world. Here, we will learn about qr code and how it works.

Qr codes can be found in many shops today.

A QR code, also known as “Quick Response code," is a two-dimensional barcode that was initially created in Japan in the 1990s. QR codes are designed to store information in a machine-readable format, and they have become increasingly popular for various applications due to their ability to store a wide range of data types.

 

The working of QR code:

Generation of a Payment QR Code:

The recipient (merchant, individual, or organization) generates a QR code that contains payment information. This QR code is usually unique to each transaction and may include details like the recipient's payment address, transaction amount, and a description of the payment.

 

Customer Scans the QR Code:

The customer, using a smartphone or other device with a QR code scanner app, scans the QR code presented by the recipient.

 

QR Code Reader App Decodes the Information:

The QR code reader app on the customer's device decodes the payment information contained within the QR code. This information may include the recipient's payment address or identifier, the transaction amount, and any additional details.

 

Authentication and Confirmation:

Depending on the payment method and the app used, the customer may be required to authenticate the transaction, often through a PIN, fingerprint, or other security measures. This ensures that the transaction is authorized.

 

Payment Processing:

After authentication and confirmation, the payment app or service processes the transaction. This may involve connecting to the customer's bank or financial institution to transfer the funds to the recipient's account.

 

Notification and Receipt:

Both the customer and the recipient typically receive notifications or receipts confirming the successful completion of the transaction. These notifications may be in the form of email, SMS, or within the payment app itself.

 

Funds Transfer:

This may happen in real-time or within a short processing window, depending on the payment service and banking infrastructure.

 

Transaction Records:

Transaction records are stored within the payment app or service, allowing both the customer and the recipient to track their payment history.

 

Completion of Transaction:

The transaction is considered complete, and the customer can continue with their purchase or payment.

 

Types of QR code payments:

Person-to-Person (P2P) Payments:

These are individual-to-individual transactions that allow people to send money to each other using QR codes. Users can create and share QR codes to request or send money to friends or family.

 

Merchant Payments:

Businesses, shops, and service providers can generate QR codes for customers to scan and make payments for goods and services. This simplifies the checkout process and eliminates the need for physical cash or credit cards. Common examples include Google Pay and Apple Pay.

 

Bill Payments:

Utility companies, governments, and organizations can generate QR codes for bills and invoices, allowing customers to scan the code and make payments quickly. This is commonly used for electricity, water bills, tax payments, online shopping etc.

 

Donations and Fundraising:

Nonprofit organizations and charities use QR codes to accept donations. Supporters can scan the code to contribute to a cause they care about.

 

Transportation and Ticketing:

QR codes are used for ticketing and transportation services. Passengers can purchase tickets or check in for flights, trains, buses, and more by scanning QR codes.

 

Secure Access and Authentication:

QR codes can serve as a secure means of authentication, such as for two-factor authentication (2FA) during login or access control for secure facilities.

 

Loyalty and Reward Programs:

Businesses use QR codes to reward loyal customers with discounts, points, or special offers. Customers can scan codes to accumulate rewards.
