A QR (Quick Response) code is a two-dimensional barcode that stores information like URLs, text, contact details, or WiFi credentials. Invented in 1994 by Denso Wave, QR codes can be scanned by smartphone cameras to instantly access the encoded information without typing.

How do I scan a QR code?

Most modern smartphones can scan QR codes using the built-in camera app—just point at the code and tap the notification. For older phones, download a QR scanner app. iPhone users can use the Camera app directly. Android users may need to enable Google Lens or use the camera's built-in scanner.

What can I put in a QR code?

QR codes can encode: URLs/website links, plain text, contact information (vCard), email addresses, phone numbers, SMS messages, WiFi network credentials, calendar events, geographic locations, and app store links. The data limit is about 3KB, or roughly 4,296 alphanumeric characters.

Static QR codes (like those generated here) never expire—the data is encoded directly in the pattern. However, if the QR code links to a URL, the destination website could go offline. Dynamic QR codes, offered by some services, can be edited but may expire based on the provider's terms.

What size should my QR code be?

QR code size depends on scanning distance. The general rule: minimum size should be 1/10th of the scanning distance. For handheld scanning (1 foot), minimum 1 inch. For posters (3 feet), minimum 3 inches. For billboards (30+ feet), minimum 3+ feet. Always test scanning before printing.

QR Code Generator

QR codes store data in a 2D barcode pattern. They can encode URLs, text, contact info, WiFi credentials, and more. Higher error correction levels allow damaged codes to still scan but reduce data capacity.
