What Is a QR Code?

A QR (Quick Response) code is a two-dimensional barcode invented in 1994 by Denso Wave for tracking automotive parts. Unlike traditional barcodes that store data in one direction, QR codes encode information both horizontally and vertically, allowing them to hold thousands of characters in a small square graphic.

Today QR codes are everywhere, from restaurant menus and payment terminals to event tickets and product packaging. Any smartphone camera can scan them instantly, making QR codes one of the most frictionless ways to bridge print and digital experiences. They support URLs, plain text, WiFi credentials, contact cards, and more.

Popular Use Cases

Marketing and Print Materials

Link flyers, posters, and business cards to landing pages, portfolios, or promotional offers with a single scan.

Restaurant and Retail Menus

Replace physical menus with scannable codes that link to always-updated digital menus, reducing print costs.

WiFi Network Sharing

Encode your network name and password into a QR code so guests connect instantly without typing credentials.

Event Ticketing

Generate unique QR codes per attendee for fast check-in at conferences, concerts, and sporting events.

Product Packaging

Link to user manuals, warranty registration, or nutritional information directly from the product label.

QR Code Best Practices

Choose the Right Error Correction

Use Level M (15%) for digital screens and Level H (30%) for printed codes that may get scratched or partially covered.

Test Before Printing

Always scan your QR code on multiple devices and apps before sending it to print to catch encoding errors.

Keep URLs Short

Shorter data produces simpler QR patterns that are easier to scan. Use URL shorteners for long destination links.

Maintain Sufficient Contrast

Dark modules on a light background scan most reliably. Avoid low-contrast color combinations that confuse readers.
