What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that can store information like URLs, text, contact details, or WiFi credentials. First invented in 1994 by a Japanese company for tracking automotive parts, QR codes have become ubiquitous in marketing, payments, and everyday convenience.
Unlike traditional barcodes, QR codes can store much more data and can be scanned from any angle. Modern smartphones can read QR codes directly through their camera apps—no special software needed.
Common Uses for QR Codes

Let guests connect to your WiFi without typing long passwords. Perfect for homes and businesses.
Mobile payment apps like Venmo, WeChat Pay, and many others use QR codes for quick transactions.

Frequently Asked Questions
Do QR codes expire?
Static QR codes (like those generated here) never expire. The code itself is just encoded data. However, if you link to a URL and that website goes down, the QR code will still work but lead to a dead page.
How much data can a QR code store?
A QR code can store up to 4,296 alphanumeric characters or 7,089 numeric digits. For URLs, keep them under 2,000 characters for best scanning reliability.
Is my data stored when I generate a QR code?
No. QR code generation happens entirely in your browser. Your data never leaves your device and is not stored on any server.
