QR Code Security: How to Protect Yourself and Your Business 

QR codes have become everywhere — on products, ads, and payments. But along with convenience comes risk: scammers can create malicious or fake QR codes to steal data or infect devices. 

What threats exist? 

Phishing — a QR code leads to a fake website asking for personal info or passwords. 

Malware — scanning can trigger downloading viruses or trojans. 

Information substitution — a fraudulent code disguised as legitimate. 

How to spot a dangerous QR code? 

Be cautious with codes in untrusted places — suspicious stickers, flyers, or unknown emails. 

Check the link if your scanner shows the URL before opening. 

Use apps with security features that warn about suspicious sites. 

How to protect your business? 

Use dynamic QR codes that allow changing the destination link and blocking harmful redirects. 

Add protections — passwords, expiration dates, scan alerts. 

Educate employees and customers to verify codes before scanning. 

QR codes are a handy tool but require attention to security. Proper precautions help avoid scams and maintain customer trust.
