About QR Codes
QR (Quick Response) codes are two-dimensional barcodes that can store text, URLs, contact info, Wi-Fi credentials, and more. They were invented in 1994 by Denso Wave for tracking automotive parts and are now used everywhere from restaurant menus to payment systems.
Error correction allows QR codes to be read even when partially damaged or obscured. Level L recovers ~7% of data, M ~15%, Q ~25%, and H ~30%. Higher levels make the code larger but more resilient — use H if you plan to overlay a logo.
Capacity depends on the data type and error correction level. A Version 40 QR code (the largest) can hold up to 4,296 alphanumeric characters or 2,953 bytes of binary data at the lowest error correction level.
Common uses: URLs (https://...), plain text, email addresses (mailto:...), phone numbers (tel:...), SMS (smsto:...), Wi-Fi credentials (WIFI:T:WPA;S:network;P:password;;), and vCards for contact sharing.
What is a URL QR code?
A URL QR code encodes a web address into a two-dimensional barcode that smartphones and scanners can read instantly. When scanned, the device opens the encoded URL in its default browser. URL QR codes are the most common type, accounting for the majority of QR code usage worldwide.
Common use cases
URL QR codes are used on business cards and flyers to link to websites, in restaurants for digital menus, on product packaging for manuals or registration pages, and in marketing campaigns to bridge print media with online content. They are also common at events for sharing Wi-Fi login portals and registration links.
Frequently Asked Questions
Do URL QR codes expire?
Static QR codes that encode the URL directly never expire — the data is embedded in the image itself. However, dynamic QR codes that redirect through a third-party service may expire if that service is discontinued.
What is the maximum URL length for a QR code?
QR codes can encode up to about 4,296 alphanumeric characters, but longer URLs produce denser codes that are harder to scan. Keeping URLs under 200 characters ensures reliable scanning across all devices.
