About QR Codes
How QR Codes Work
QR (Quick Response) codes are 2D barcodes that store data in a matrix of black and white squares. When scanned, they can perform various actions like opening websites, displaying text, or connecting to Wi-Fi networks.
QR Code vs Barcode
| Feature | QR Code | Traditional Barcode |
|---|---|---|
| Data Capacity | High (~7,000 chars) | Low (~20 chars) |
| Scan Direction | Omnidirectional (any angle) | Horizontal only |
| Error Correction | Yes (damaged codes still work) | No |
Types of QR Codes
Static vs. Dynamic QR Codes:
- Static: Fixed data (cannot be edited after creation). Best for permanent info like Wi-Fi passwords.
- Dynamic: Editable tracking links. Ideal for marketing campaigns.
Common QR Code Formats:
- URL QR Codes - Direct to a website (e.g., restaurant menus)
- vCard QR Codes - Share contact details instantly
- Wi-Fi QR Codes - Auto-connect users to a network
- Payment QR Codes - Used by PayPal, Venmo, and crypto wallets
QR Code Security Risks
Malicious QR Codes (Quishing Attacks)
Scammers create fake QR codes to:
- Steal login credentials (fake Wi-Fi portals)
- Install malware (malicious app downloads)
How to Scan Safely:
- Verify the Source - Don't scan random public codes
- Use a Secure Scanner - Apps like Kaspersky QR Scanner check for threats
- Preview Links - Some scanners show the URL before opening
