What is a QR Code and Why You Should Be Cautious

A QR code (short for Quick Response code) is a type of two-dimensional barcode that stores information like text, URLs, or other data. You can scan it with your smartphone or a QR code reader to quickly access websites, menus, apps, and more. It’s a fast way to connect the physical world to the digital one.

Common uses for QR codes include:

Opening websites or apps – Scan to visit a webpage or download an app.

Connecting to Wi-Fi – Some QR codes store network info so you can join without typing in the password.

Making payments – Used for secure, contactless transactions.

Sharing contact info – Great for business cards or event invites.

Accessing digital content – Like restaurant menus or product details.

Authentication – Used for secure logins and account verification.

Marketing – Promos, discounts, and product info in ads.

But QR codes can also be used in scams — a tactic known as “quishing.”

Because you can’t see where a QR code leads until you scan it, scammers use this to trick people into visiting fake websites, downloading malware, or giving up personal info.Because you can’t see where a QR code leads until you scan it, scammers use this to trick people into visiting fake websites, downloading malware, or giving up personal info.
 

Common QR code scams to watch out for:

Tampered QR codes in public places – Scammers stick fake codes over real ones (like on parking meters or menus) to steal payment info.

Phishing texts and emails – Messages with QR codes pretending to be from delivery services or banks, leading to fake login pages.

Unsolicited packages – Some scams involve sending random packages with QR codes that lead to malicious sites.

Fake promotions – Flyers offering prizes or discounts that actually harvest your personal data.

Crypto scams – Fraudulent QR codes used to redirect crypto payments to a scammer’s wallet.

What can happen if you scan a malicious QR code?

• You might be phished into entering sensitive info on a fake site.
• Malware could be installed on your device.
• Your accounts could be compromised if login credentials are stolen.

How to protect yourself:

Inspect QR codes before scanning — especially in public places.

Avoid scanning unsolicited codes from texts, emails, or packages.

Preview the link before opening it — look for misspellings or unsecured URLs.

Verify the source — ask staff if a QR code is legit.

Use antivirus software on your phone.

Enable multi-factor authentication (MFA) on your accounts for extra protection.
