How Does QR Code Payment Technology Work?

QR code payment technology provides another alternative to cash or credit card payments. It allows customers to pay for goods and services quickly and easily using a mobile device. For merchants, providing customers with QR code payment options and other modern payment methods allows your business to appeal to a wide demographic.

Once you understand how QR code payments work, you should feel more confident about implementing this innovative payment method in your business.

How Do QR Code Transactions Work?

QR code payments use information contained in a barcode-like image to complete a transaction. A smartphone user can use a QR code app both to make and accept payments.

Businesses need a merchant account and merchant services in order to accept QR code payments that involve credit or debit card details.

How QR Code Payments Are Made

There are two models of QR code payment processes: the merchant-presented and the customer-presented. Each of which can use static or dynamic QR codes.

Merchant-Presented QR

The customer scans a QR code provided by the merchant. Once scanned, the customer is directed to a payment page where they enter their payment details. They can alternatively use a pre-installed payment solution like Apple Pay, Google Pay, Venmo QR code payments, or PayPal QR code payments to complete the transaction.

Customer-Presented QR

The customer generates a QR payment code that links to their card details. The merchant scans this code to finalise the transaction through their payment gateway. This method is common in Asia and in payment app-based purchases.

Both merchant-presented and customer-presented transactions may be static or dynamic:

Static QR Code

• Contains fixed information such as client ID or merchant details
• Can be scanned numerous times
• Does not include transaction details such as purpose or amount
• Cheaper and simpler to use

Dynamic QR Code

• Generated uniquely for each transaction
• Includes transaction details such as purpose and amount
• Requires an app that generates new codes
• More secure because it is harder to copy

How to Provide a QR Code Payment Option in Your Business

Follow these steps to integrate QR payment technology in your business:

1. Set up an account with a QR code app to generate a unique QR code for your business. Ensure your provider supports the payment options you need (European Payments, SEPA, etc.).
2. Display QR codes somewhere prominent in your business (such as at the till). If you are an online business, place unique QR codes on each product page or at the checkout.
3. Provide training for your staff to troubleshoot and help your clients with any QR-related questions. Make sure to run internal tests before launching.
4. When a customer pays using a QR code, they will scan it using their smartphone camera, generally through a QR code app. Once the customer has scanned the code, they will be taken to a separate window or app to complete the transaction. The app may be linked to one of their bank accounts or a payment app.
5. If the customer uses a mobile wallet, you can also scan a QR code that the customer generated using the app. For this, your business will need either an internet-connected mobile device or a barcode scanner that is able to scan QR codes.
6. It is important to ensure internet connectivity and to track results and monitor workflow to ensure a fine-tuned quality service.

If you need more assistance with QR code payment systems, ask your payment processor about QR code payments. They may offer an app or plugin to help you integrate this payment option seamlessly into your business.

What Are the Benefits of QR Code Payments?

Businesses that accept payments via QR codes (as with payment by text) provide their customers with a contactless payment method that’s easy and stress-free. Ultimately, merchants should provide as many payment methods as they cater to a wide range of customers. Offering diverse payment methods delivers an optimal customer experience and solutions tailored to their needs.

The following are some additional benefits of QR code payments:

• Easy to set up. Accepting credit and debit card payments often means purchasing card readers, especially if you have a brick-and-mortar store. In comparison, setting up QR payment services is extremely easy, as no additional hardware is required.
• Flexibility. Because scanning QR codes only requires downloading an app, it is easy to roll out this payment method in multiple locations as well as in your online store.
• Answering customer demand. QR codes are becoming more popular. Providing customers with this option should mean happier customers, more conversions, fewer abandoned carts, and more revenue for your business.
• Streamline the payment process for the customer and the business. Because the whole payment process is conducted via payment apps on smartphones, there’s no need for physical loyalty cards or receipts. Customers can sign up for loyalty programs via their smart devices, streamlining the process and keeping everything in one place.
• Lower transaction costs. QR codes typically have lower transaction costs than card terminals for small businesses.
• Faster and more convenient. Scanning a QR code is fast and provides a contactless payment solution.
• Data storage: QR codes store a large volume of data.
• Digital and paper options: QR codes can be scanned from screens or paper, making it easy to make mobile payments no matter where you are.
• Resilient: If part of the code gets damaged, it can still be read, allowing customers to make in-person or online payments even if the code isn’t 100% intact.
• Refunds and reconciliation: Dynamic QR codes enable refunds and real-time reconciliation.

Businesses also need to acknowledge that the use of QR codes will likely become more common in the future and start to prepare for that eventuality now. According to the World Bank, steps are being taken in Europe to unify the payment landscape by establishing a cross-platform network, meaning that payment processing in Europe is becoming easier for both customers and businesses. Digital payment methods like QR code technology are poised to become an important part of the payment landscape of the future.

Security and Fraud Prevention

QR payments are considered a secure payment option. However, it is essential to be aware of potential risks in order to mitigate issues.

One scam that is becoming more prevalent is “Quishing” (QR phishing), where the QR code is replaced or modified to send customers to fraudulent websites. In Europe, regulations and guidelines have been put in place to strengthen security in QR payments, including verification and authentication.

Ensure security by following these steps:

1. Use only trusted providers (banking platforms or verified fintech).
2. Use dynamic codes (one-time codes tied to a transaction reduce fraud).
3. Secure display and monitor (replace damaged codes, do not share QR outside of context, flag any irregular transactions).
4. Educate customers (remind them to scan codes from verified sources).
5. Stay compliant (ensure data privacy standards are met).

Do QR Payments Have Any Disadvantages for Businesses?

Though accepting QR code payments has several advantages for both businesses and customers, businesses should also be aware of the limitations of this payment method. The following are a few things to keep in mind:

• Customers must have the relevant technology to use QR codes. Reading QR codes requires a smartphone that can scan the code and may require the customer to download an app.
• Requires an internet connection. Customers with incompatible mobile phones or businesses in places with poor signal or no access to Wi-Fi may have problems accessing the content behind the QR code.
• Mistrust of unfamiliar websites. Scanning a code that leads a customer to an unfamiliar site may cause suspicion or mistrust. Customers may be unwilling to navigate to unknown sites or content that potentially puts their data at risk.
• Security and operational risks. Fake or tampered QR codes, as well as poorly generated QR codes, open you up to fraud or failed transactions. Businesses must ensure that QR codes are secure and clear to prevent misuse and potential financial loss.
• Compliance: Companies must ensure compliance with security standards and regulations, including data protection and industry guidelines. Failure to do so puts you at risk of fines and legal liability.

Other Ways to Use QR Codes to Boost Business

QR codes aren’t only useful for accepting payments; they can be used in many ways to boost business. Because a QR code is essentially a way for a customer to open a web page, QR codes can be used to direct customers to anything that’s useful to the business. This includes:

• Link to business website: Directing customers to homepages, product pages, or promotional landing pages.
• Distribute coupons and special offers: Saving on printed material and encouraging foot traffic with QR-linked discounts.
• Provide product manuals or instructions: Providing easy-to-access digital guides and information.
• Offer quick customer service access: Linking directly to contact and support pages or live chats.
• Promote app downloads: Directing customers to easy downloads for business mobile apps.
• Encourage customer engagement: Using QR codes to provide discounts or interactive content.
• Support loyalty programs and reviews: Linking to digital loyalty cards or review platforms to boost repeat business.
• Enable cross-selling or upselling: Suggesting related products or services directly through QR-linked content.
• Facilitate advanced payments: Offering crypto-to-fiat conversions, government payments, or other emerging payment solutions.
• Enhance interactive experiences: Connecting customers to AR content, virtual demos, or other interactive marketing campaigns.

Remember that while QR code technology benefits your business in many ways, not everyone will be comfortable using this technology. Accessibility and inclusivity are important.

Businesses with elderly customers, customers without smartphones, or people who simply prefer more traditional ways of interacting with your business are a significant demographic that you shouldn’t forget about. It makes good business sense to provide QR technology for customers who wish to use it, while not abandoning more traditional payment or communication methods.

QR Payments Are a Modern Solution for Modern Customers

Choosing to accept QR code payments is a savvy move both for brick-and-mortar and online businesses. According to Verified Market Reports, the market revenue for QR payments was valued at $4.5 billion in 2024 and is projected to reach $14.8 billion by 2033.

Being willing to diversify the way you collect payments means that you don’t shut the door to any potential customers, therefore reducing lost sales. You also encourage customer loyalty by providing a speedy and convenient checkout experience.

Though offering QR code payments is an excellent option for many businesses, they should be offered alongside more traditional payment methods rather than replacing them. Your merchant services provider will explain everything you need to know about accepting payments via QR codes to provide the best possible customer experience.
