These scams may attempt to:

- Redirect to fake payment pages

Knowing how to identify fake QR codes before scanning can help protect your personal and financial information.
How QR Code Scams Work
Scammers often place fake QR code stickers over legitimate ones.
Common targets include:
- Restaurant menus
- Parking payment machines
- Public charging stations
- Event posters
- ATMs
- Shopping malls
- Public advertisements
When scanned, the fake code redirects users to a phishing website instead of the legitimate destination.
How to Identify Fake QR Codes Before Scanning
Step 1: Check for Stickers Placed Over Original QR Codes
Look closely at the QR code.
Warning signs include:
- Uneven stickers
- Peeling edges
- Multiple layers
- Poor print quality
- Misaligned labels
A sticker covering another QR code is a major warning sign.
Step 2: Preview the Website Before Opening
Most Android phones display the website address before opening it.
Carefully review the URL.
Look for:
- Correct domain name
- HTTPS security
- No unusual characters
- No random numbers or symbols
If the web address looks suspicious, don’t open it.
Step 3: Watch for Misspelled Website Names
Scammers often create fake websites with similar names.
Examples:
- g00gle.com
- paytm-secure.xyz
- amaz0n-login.net
Always verify the official domain before entering any information.
Step 4: Avoid QR Codes in Suspicious Locations
Be cautious with QR codes found on:
- Lamp posts
- Random flyers
- Unverified advertisements
- Unknown emails
- Social media comments
Only scan QR codes from trusted sources.
Step 5: Be Careful with Payment QR Codes
Before making a payment:
- Verify the merchant’s name.
- Confirm the payment amount.
- Double-check the recipient information.
- Cancel the transaction if anything looks unusual.
Step 6: Don’t Download Unknown Apps
If a QR code immediately asks you to download an APK or install an unfamiliar app, avoid it.
Install apps only from the Google Play Store or other trusted sources.
Step 7: Use Google Safe Browsing
If a scanned QR code opens a website that triggers browser security warnings, leave the page immediately.
Google Safe Browsing helps detect many malicious websites.
