QR codes are popping up everywhere—from restaurant menus to payment apps, marketing flyers, and more. As they grow in use, the security and privacy of QR codes has become a major concern.

"QR codes aren't dangerous by themselves. But misusing them can introduce serious risks."Scanova



Are QR Codes Secure? Understanding QR Code Safety

QR codes are squares that hold data. Phones scan them to connect to websites, trigger app installs, or display messages. They're used everywhere—from stores to airports.

QR codes:

  • Store data in a 2D visual square
  • Are scanned by phone cameras
  • Link to websites, files, forms, or payment platforms

Are QR codes secure? Yes—and no.

They are only as secure as the link inside them. The QR code itself isn't a virus, but it can lead to dangerous content.

Common vulnerabilities include:

  • Malicious links to phishing pages
  • Apps that install malware
  • Pre-written messages for fraudulent use

It's a myth that a QR code alone will "infect" your phone. But if it sends you to a fake site, the consequences can be damaging.

"The QR Code is not dangerous itself, but the information it gives access to could be."Scanova



QR Code Phishing Risks & Other Common Threats

QR Code Phishing Risks

Phishing with QR codes = "Quishing."

Attackers swap safe QR codes with fake ones. These lead you to fake websites that look real—banks, login forms, etc.

How phishing QR codes are spread:

  • Stickers pasted over official codes (menus, parking meters)
  • Emails or texts with QR codes claiming to offer rewards
  • Posters in public spaces asking you to "scan to win"

Real-world example:

  • Criminals have placed fake QR code stickers on public parking signs, collecting payment info from people unknowingly.

What can happen:

  • Passwords stolen
  • Bank accounts accessed
  • Phones compromised

Quishing is growing fast and hard to detect. (Scanova)

Malicious QR Codes

Not all fake QR codes try to fool you with phishing. Some:

  • Force malware downloads
  • Ask users to install shady apps
  • Trigger pre-filled texts or emails for scams

Risks include:

  • Identity theft
  • Ad fraud
  • Ransomware

Sometimes it's not what the QR code is—it's what it opens that's the risk.

How to Avoid Malicious QR Codes

Best Practices for Users

To avoid scams, follow these steps:

  • Scan codes only from trusted sources: official signage, known companies
  • Use QR reader apps that show you the URL preview
  • Don't scan random codes on walls or public flyers
  • Look for tampering: stickers on top of real QR codes = red flag
  • Always review the link before clicking—look for odd domains or misspelled brand names

Always verify the link before proceeding. (Scanova)

Technological Solutions

  • Install mobile security apps to check links before opening
  • Turn on phone settings that ask for confirmation before launching URLs
  • Keep your device updated to prevent known exploits
  • Use enterprise QR monitoring tools that can detect odd usage patterns


Secure QR Code Creation: Tips for Safety

Guidelines for Creating Safe QR Codes

Make your QR codes safe to scan by:

  • Using trusted QR code generators (like Scanova)
  • Making sure destination URLs use HTTPS encryption
  • Checking links often to ensure they still go to the right place
  • Avoiding too much personal data in codes
  • Disabling or updating old codes that are no longer needed

Use platforms like Scanova that follow GDPR and ISO 27001:2022.

Advanced Security Measures

For better secure QR code creation:

  • Use dynamic QR codes—they can be turned off or changed later
  • Require user login or multi-factor authentication when needed
  • Set a time limit or session expiry on your codes

This prevents attackers from reusing old codes.



Organizational QR Code Safety for Businesses

For Businesses and Organizations

Companies should have rules for safe QR code use:

  • Control who can make QR codes internally
  • Train staff on risks
  • Watch your QR codes for strange traffic or replacements
  • Set a "kill switch" process if a malicious code is found

QR code safety is a shared responsibility.

Compliance and Standards

Some companies must also follow data laws:

  • GDPR (Europe)
  • CCPA (California)
  • ISO standards for QR code management

Industries like finance and healthcare should:

  • Perform external QR security audits
  • Follow protocol for handling personal data


Conclusion

Are QR codes secure? Only when used correctly.

QR codes are not harmful by themselves. But poor handling opens the door to security and privacy risks. With QR code phishing risks on the rise, staying informed is vital.

To stay safe:

  • Only scan trusted codes
  • Use protection software
  • Monitor and audit QR code links
  • Invest in secure QR code creation

The convenience of QR codes is huge—but only when used wisely.
