What is a QR Code and How Does It Work?

QR (Quick Response) codes have become ubiquitous in our daily lives. From restaurant menus to payment apps, these square barcodes store information that can be read instantly by smartphone cameras.

How QR Codes Work

A QR code is a two-dimensional barcode that encodes data in a pattern of black and white squares. Unlike traditional barcodes that store data in one direction, QR codes store data both horizontally and vertically, allowing them to hold much more information.

What Can You Encode?

**URLs**: Link to websites, landing pages, or social profiles

**Text**: Plain text messages up to about 4,000 characters

**Contact Info**: vCard data for easy contact saving

**WiFi**: Network name and password for easy connection

**Email**: Pre-filled email addresses and subjects

Why Are QR Codes So Popular?

1. **Contactless interaction**: Essential since the pandemic

2. **Easy to create**: Free tools generate them instantly

3. **Error correction**: QR codes work even if partially damaged

4. **Versatile**: Work on screens, print, packaging, and more
