2. What is a QR Code? (Detailed Explanation)
A QR code (Quick Response code) is a two-dimensional barcode that stores data in a square grid. Unlike traditional barcodes, QR codes can hold:
- Website URLs (e.g., https://trezolsmart.com)
- Contact details (vCard format)
- Wi-Fi credentials (Network name & password)
- Text messages (Pre-written SMS)
- Payment links (UPI, PayPal, etc.)
How Do QR Codes Work?
- Pattern Recognition – Smartphone cameras detect the square alignment markers.
- Data Decoding – The scanner reads black-and-white modules (dots).
- Action Triggered – Opens a website, saves a contact, or displays text.
📌 Fun Fact: The first QR code was invented in 1994 by a Japanese company for tracking car parts!
