The Retail Rush to Embrace QR Codes

The integration of QR codes into retail environments is rapidly accelerating. While approximately 25% of US retailers are either implementing or planning to introduce QR code payment systems within the next three years, a slightly larger percentage of UK merchants are following suit. however, the utility of QR codes extends far beyond mere payment processing. A significant majority, exceeding 80%, of retailers believe that QR code scanning for product-level information is crucial for fostering customer loyalty. This perspective suggests a widespread belief in the power of QR codes to enhance the consumer experience.

The Evolution from Barcodes: A Data-Rich Future?

Major supermarket chains in the UK, including Tesco, Morrisons and Ocado, are actively experimenting with QR codes on everyday items like milk and water bottles. This shift reflects a growing consumer demand for complete product information. Studies indicate that approximately three-quarters of UK consumers prioritize product information when making purchasing decisions, and nearly two-thirds are willing to pay a premium for products that offer detailed insights. This trend is driving the anticipated obsolescence of customary linear barcodes in favor of QR codes,which possess a significantly greater capacity for data storage. A survey of UK retail executives revealed that a considerable 41% believe QR codes will replace barcodes entirely within the next five years.

The Dark Side of QR Codes: A Gateway to Fraud

Imagine a scenario where every milk carton is adorned with a QR code, and malicious actors begin replacing thes codes with their own fraudulent versions. While this may seem far-fetched, it highlights the inherent security vulnerabilities associated with QR codes. They are increasingly becoming a prime target for both marketers and fraudsters. The basic issue is the lack of inherent security; anyone can generate a QR code and affix it to virtually any surface, be it a milk carton, a parking sign, or a bank advertisement. The proliferation of QR code-based crime is a growing global concern.

Consider this example:

Indian fraudsters snuck out in the night to paste their own QR codes over the QR codes outside shops in order to divert the payments meant for shopkeepers into their own accounts!

Concerns about QR code security have persisted for years. While they offer convenience and efficiency, their widespread adoption has been accompanied by a surge in security-related issues.

Expanding the deployment of QR codes without implementing robust security measures, such as digital signatures, is highly likely to exacerbate the problem of fraud. This is not merely a hypothetical concern; it is indeed a reality that has already unfolded in various parts of the world, where criminals are exploiting QR codes for both online and offline fraud:

• In China, scammers have been caught placing fake parking tickets — complete with QR codes for easy mobile fine payment — on parked cars;
• In Spain, the Organisation of Consumers and Users (OCU) has just issued a warning about fake QR codes at electric vehicle charging stations;
• In the Netherlands, a QR code scam exploited a legitimate feature within a mobile banking submission to swindle the bank’s customers.
• In Germany, phony emails containing QR codes lured eBanking customers to malicious websites under the guise of reviewing privacy policy updates to their accounts. Banks such as Santander and HSBC have joined the UK National cyber Security Centre and Federal Trade Commission (FTC) in sounding the alarm about this kind of threat, where criminals send a QR code in a PDF attached to an email to avoid corporate cybersecurity defenses.
• In the US (and the UK), criminals have been particularly active around car parks, pasting stickers of malicious QR codes onto car parking machines, fooling drivers into entering bank account or credit card details into a fake phishing site.

Regulatory bodies have issued warnings about QR code phishing scams, frequently enough referred to as “quishing,” which are increasingly bypassing corporate cyber defenses and deceiving customers into divulging their financial information.These scams are particularly effective because the codes are unreadable to the human eye, preventing consumers from discerning their true destination. Despite these warnings, QR code scams now account for more than a fifth of all online scams. The situation has become so dire that some parking facilities have ceased accepting QR codes altogether.

the Technological Alternative: Object Recognition and AI

The fundamental question is: why rely on QR codes at all? Perhaps it’s time to consider phasing them out rather than inundating every conceivable surface with them. A decade ago, Masahiro Hara, the inventor of QR codes, predicted that they would be superseded by advancements in mobile phone cameras and artificial intelligence.His reasoning was that smartphones would eventually be able to recognize objects and read labels directly, eliminating the need for QR codes. This prediction is proving to be remarkably accurate.

Consider the example of paying for parking. Modern smartphones are capable of determining location, time, and parking charges by analyzing visual information or accessing online databases. They can even integrate with personal calendars to estimate parking duration. This approach is not only more convenient but also more resistant to fraud.

Rethinking the Role of QR Codes in the Modern World

While secure QR codes with digital signatures exist, they are not widely deployed in the mass market. The QR codes found on everyday items like milk cartons are designed to be read by any camera phone, and neither Apple nor Android currently offer mechanisms for verifying the security of QR codes before redirecting users to a URL or downloading an app.

Instead of relying on QR codes, smartphones and supermarket checkout systems could easily recognize a milk carton, read it’s label, and access online information about its production, ethical sourcing, and corporate affiliations.Rather than applauding the increased use of QR codes, we should be mindful of the “attack surface that is presented by malicious QR code usage” as Davey Winder just called.

Rather of adding another potential entry point for fraud into our already vulnerable cyber infrastructure, we should be exploring ways to eliminate QR codes altogether.
