The Rise of QR Codes and Their Cybersecurity Risks

QR codes have exploded in popularity, bridging the gap between the physical and digital worlds. From contactless payments to restaurant menus and event check-ins, QR codes offer convenience—but also introduce cybersecurity concerns.

So, are QR codes safe? The short answer is: they can be. But only if you understand the risks and take appropriate precautions. Like any digital tool, QR codes can be exploited by cybercriminals if users aren’t aware of how to spot and prevent potential threats.

How QR Codes Work—and Where They Can Go Wrong

QR codes are scannable two-dimensional barcodes that can store various types of data—typically URLs, payment information, or contact details. When scanned, the code directs users to a linked action, often opening a browser or app.

Here’s the catch: unlike a traditional hyperlink you can hover over and examine, scanning a QR code often bypasses user scrutiny. That’s what makes them vulnerable to misuse.

Common issues include:

• QR codes that link to malicious websites
• Embedded malware downloads
• Codes that trigger phishing scams
• Spoofed business pages or login screens

 

Real-World QR Code Scams You Should Know About

Parking Meter Scam in Austin, Texas

Cybercriminals placed fake QR code stickers on public parking meters. Drivers were redirected to a scam website that captured their payment details.

COVID-19 Health Survey Scam

Fake QR codes were distributed pretending to be official health check-ins, leading users to phishing sites requesting personal data.

Restaurant Menu QR Codes

Unsuspecting diners scanned tampered codes on tables that redirected to fake food ordering portals mimicking well-known apps.

These examples highlight why understanding QR code safety is essential for both consumers and businesses.

How to Tell If a QR Code Is Safe

When you encounter a QR code, use these cybersecurity tips before you scan:

• Examine the placement: Is the QR code printed directly on the sign or is it a suspicious-looking sticker?
• Preview the link: Most smartphones will show the destination URL. Make sure it’s legitimate before tapping.
• Avoid shortened links: If a QR code leads to a bit.ly or other shortened URL, it’s harder to verify. Avoid if unsure.
• Look for HTTPS: Always check for secure encryption (https://) in the browser after scanning.

What Happens If You Scan a Malicious QR Code?

A malicious QR code can do serious harm in seconds. Here’s what could happen:

• Redirect you to a phishing site that mimics a trusted login page
• Install spyware or ransomware on your device
• Capture login credentials or credit card information
• Connect your device to a malicious server without your consent

The damage isn’t always immediate. Cybercriminals often use QR codes to quietly gain access and launch attacks later.

Should You Use QR Codes in Emails or Flyers?

Yes—but with precautions. QR codes in printed flyers, posters, or emails are safe if you:

• Generate them with a secure platform
• Use branded, traceable links
• Place them where tampering is unlikely
• Educate your audience on how to recognize safe QR codes

Adding a short domain or branding on the flyer can build trust and reduce the chances of the code being spoofed.

How to Protect Your Customers from Fake QR Codes

If you run a business, protecting your customers should be a priority. Here’s how:

• Use tamper-evident designs for your QR posters and signage
• Print QR codes directly on materials—avoid using stickers in public areas
• Register branded QR domains through Qrizo
• Educate your customers with safety tips or brief instructions next to the QR code
• Enable real-time QR analytics to detect anomalies

QR Codes and Mobile Device Security

Even the most secure QR platform can’t help if your phone is compromised. To stay safe:

• Install a reliable antivirus or anti-malware app
• Keep your phone’s OS and apps updated
• Turn off automatic actions (like Wi-Fi join requests) triggered by QR codes
• Disable auto-opening links after scanning

Cybersecurity starts with individual awareness, especially in mobile-first environments.

Final Thoughts: Are QR Codes Safe in 2025?

Yes—if used wisely. QR codes are a powerful, flexible, and contactless technology that’s here to stay. But like any tool, they’re only as safe as the hands that use them. Whether you’re a user or a business, staying informed about cybersecurity best practices is essential.
