How QR Codes are Redefining Digital Payments

Imagine you're in a cozy coffee shop. The smell of coffee fills the air, promising a much-needed break from the hustle outside.

You order your favorite brew, realizing you've left your wallet at home. Panic sets in… but then you spot a QR code at the counter, a beacon of modern convenience.

With a simple scan of that QR code using your smartphone, you can pay through your digital wallet.

What changes?

A new alternative to traditional cashless methods like credit and debit cards that can even make international money transfers.

QR codes help overcome challenges such as payment methods like-

Against this backdrop, QR code payments are rising globally, especially in Asia and Africa.

What is a QR Code?

A QR code, or Quick Response code, is a two-dimensional barcode that can store various information, from URLs to payment instructions, within its black and white squares. Such a code is designed for quick readability and high storage capacity that can scanned using smartphones or dedicated QR scanning devices.

There are two major types of QR codes.

Static QR codes

Static QR codes encode information directly into the code itself. Once created, the information cannot be changed or updated. They're often used for fixed information, such as a link to a restaurant's menu, a Wi-Fi network password, or contact details.

Dynamic QR Codes

Dynamic QR codes work by encoding a redirect URL into the QR code, which points to the actual information or links online. This allows owners to change or update the information behind the URL without altering the QR code itself. They are particularly useful for marketing campaigns, tracking and analytics, or any application where the information needs to be updated regularly.Here is a quick difference between the two

Aspect	Static QR Code	Dynamic QR Code
Content Editing	It cannot be edited; a new QR code is needed for updated information.	It can be edited; the destination URL can be changed without altering the QR code.
Tracking	No tracking or analytics are available.	Allows for tracking and analytics of scans.
Usage	Ideal for permanent information or one-time use.	Best for marketing, where information might need updates or tracking is desired.
Cost	Usually free to create and use.	It may require a subscription for advanced features like tracking.

Evolution of QR codes

Initially developed in 1994 to enhance the efficiency of manufacturing processes, QR codes quickly outgrew their original purpose.

Before the QR code became one of the fast-growing digital payment trends, it was a universal tool for data sharing and transactions. Significant milestones in barcode technology set the stage for their development.

From the Universal Product Code (UPC) in the 1970s to the creation of QR codes in the 1990s, the evolution reflects a relentless pursuit of efficiency and versatility in data encoding.

Here's a brief look at the pivotal phases in this evolution, marking the transition from simple barcodes to the sophisticated, data-rich QR codes we rely on today. za

QR Code Standards for Payments

QR Code technology is pivotal in facilitating secure and efficient digital transactions. It operates within standards that ensure interoperability, security, and user trust.

EMVCo's QR code specification for payment systems is a critical standard in this domain, which plays a significant role, especially in secure payments.

EMVCo is a consortium with backing from major payment networks like Visa, MasterCard, American Express, and Discover. This will help develop specifications to follow QR code standards for payment, which will secure QR-based payment solutions globally.

The EMV QR code specification for payment systems delineates two main types:

The specifications include encryption, data integrity, and tokenization guidelines, essential for protecting sensitive information like card numbers and personal details.

How Does a QR Code Work for Payments?

A QR code acts as a bridge between the physical and digital worlds. It encodes information in a way that machines, particularly smartphones and tablets equipped with cameras, can decipher.

This process, especially when applied to payments, harnesses a sophisticated interplay of technology to offer a seamless transaction experience. But before exchanging payments, both parties must furnish the know-your-customer (KYC) documents. This will have third-party QR code apps implementing KYC solutions to confirm users’ identity by analyzing their identity documents online.

Capturing the Code

The payment journey begins when a user opens a QR code payment app on their smartphone to scan a QR code, which could be used for a wide range of payment options, including making a PayPal payment or settling a retail purchase.

Modern smartphones can read QR codes from physical stickers and screens. Some applications use the camera to capture the image of the QR code, which encodes data such as a URL, a merchant's payment information, or a payment request.

Decoding the Data

Once captured, the app decodes the QR code.

This is the step where the QR code is scanned by interpreting the black and white squares to extract the encoded information. Here, there is direct instruction to initiate a payment, authenticate the credentials with a payment service, or data to create a QR code for payment in a peer-to-peer transaction.

QR code specifications for payment systems govern this process and ensure the information is interpreted correctly and securely.

Initiating the Transaction

After decoding the data, the app proceeds to initiate the payment.

If the QR code is merchant-presented, the app will typically redirect the user to a payment gateway or interface, pre-filled with the merchant's payment details and the transaction amount.

There are also consumer-presented codes, where the merchant's device scans the code displayed by the customer's app, receiving the payment information directly.

Additional security measures, such as entering the PIN or biometric verification, can also authorize the transaction.

Completing the Payment

Finally, the transaction is processed through a payment gateway, which securely transfers funds from the customer's account to the merchant's.

Here, the gateway communicates with two parties to complete the payment

Once the transaction is authorized and processed, both parties receive confirmation, marking the completion of the payment process.
