Detailed Guide: How QR Codes Work

Quick Response (QR) codes are two-dimensional barcodes invented in 1994 by the Japanese automotive company Denso Wave. Unlike standard vertical barcodes that only read horizontally, QR codes encode data in both vertical and horizontal directions, storing significantly more information.

Data Structuring Formats:

URLs: Standard raw string headers (e.g. https://...). Browsers handle them as direct redirects.
Wi-Fi Networks: Uses the industry standard WIFI:S:<SSID>;T:<WEP|WPA|nopass>;P:<PASSWORD>;; structure.
Mailto Actions: Uses the standard protocol mailto:<email>?subject=<subject>&body=<body> to open the client's email application.

Contrast Best Practices:

Always ensure there is high contrast between the foreground (dark dots) and background colors. If contrast is too low, QR scanners will fail to separate the patterns. Black on a white background is the most readable combination.

Frequently Asked Questions

Are these QR codes safe to use?

Absolutely. All QR encoding and image rendering takes place right inside your browser. No contents or inputs are sent to our servers, keeping your contact details, Wi-Fi passwords, and links 100% confidential.

Which Error Correction level should I choose?

Error correction helps the QR code remain readable even if it is partially damaged or dirty. 'Low' (L) is fine for digital screens, 'Medium' (M) is good for standard use, and 'High' (H) is recommended for printing on physical items like shirts or brochures.

How do I connect to a Wi-Fi network using a QR code?

Most modern smartphones running iOS or Android can scan the Wi-Fi QR code with their default camera app. When scanned, it will prompt you with a card to automatically connect to the network without typing the password.
