The Complete Guide to QR Codes: Generation, Customization & Use Cases

What Are QR Codes?

QR (Quick Response) codes are two-dimensional barcodes that store data like URLs, text, WiFi credentials, contact cards, and more. First invented in 1994 for automotive tracking, they've become ubiquitous in marketing, payments, and everyday communication.

Types of QR Code Content

• URLs — Link to any website, landing page, or app store listing
• WiFi — Let guests connect to your network by scanning
• Email — Pre-fill recipient, subject, and body text
• Phone — Dial a number instantly
• Plain text — Store any arbitrary text message
