QR code (Quick Response code) is a two-dimensional barcode that can store various types of data. When scanned with a smartphone camera, it can open websites, connect to WiFi, add contacts, or display text. QR codes are widely used for marketing, payments, and information sharing.

How do WiFi QR codes work?

WiFi QR codes encode the network name (SSID), password, and encryption type. When scanned, the phone automatically connects to the WiFi network without manually entering credentials. This is perfect for guests or home networks.

What is a vCard QR code?

vCard is a standard format for electronic business cards. A vCard QR code contains contact information (name, phone, email, address). When scanned, it adds the contact to the phone's address book. Great for business cards and networking.

Is my data sent to a server?

No. All QR code generation happens entirely in your browser using JavaScript. Your URLs, WiFi passwords, contact information, and other data are never transmitted over the network. The tool works offline after the page loads.

What size should I use?

For printing on business cards, 300-400 pixels is good. For posters or larger displays, use 500-800 pixels. The QR code will scale proportionally. Always test the QR code before printing to ensure it scans correctly.

Can QR codes be scanned by any phone?

Most modern smartphones can scan QR codes directly with the camera app (no app needed). This includes iPhones (iOS 11+), Android phones (Android 8+), and many older devices with QR scanner apps. QR codes are universally compatible.
