Why QR Codes Feel Safe

QR codes look simple and harmless. They are just black squares on white paper. But remember: a QR code is not an image. It is a hidden link. It can open any website instantly.

The Risk Most People Forget

When you click a suspicious link, you hesitate. When you scan a QR code, you trust it. That trust gap is exactly what scammers exploit.

Common QR Code Scams

Fake Payment Codes
Scammers place stickers over real QR codes in restaurants or parking lots. Money goes directly to their account instead of the store.

Phishing Websites
The scan opens a fake login page that looks identical to your bank or app. You enter your password and hand it over without noticing.

Malware Downloads
Some codes trigger automatic app downloads or suspicious files.

Public Posters and Emails
Free Wi-Fi, prizes, coupons. These are common bait.

How to Scan Safely

Check the URL first
Preview the website before opening it.

Avoid random public codes
Especially stickers placed over existing signs.

Use official apps only
Banks and payments should open inside trusted apps.

Never enter passwords immediately
Pause and confirm the address.

The Golden Rule

Treat QR codes like links from strangers. If you wouldn’t click it, don’t scan it.

Final Thought

QR codes are powerful tools. They connect the physical world to the internet in one second. Convenience is amazing. But awareness is protection. Scan smart, not fast.
