What is a QR Code?

A QR (Quick Response) code is a 2D barcode that smartphones can scan to instantly open a URL, connect to WiFi, send an email, or dial a phone number.

Types of QR Codes You Can Create

1. URL QR Code

The most common type. Share any website link as a scannable code — perfect for business cards, posters, and packaging.

2. WiFi QR Code

Let guests connect to your WiFi by scanning a code — no more sharing passwords. Works on Android and iOS.

3. Email QR Code

Scanning opens a pre-filled email on the user's phone — great for contact forms and feedback.

4. Phone Number QR Code

Scanning dials your number directly — useful on flyers and brochures.

5. Plain Text QR Code

Encode any message, coupon code, or instructions as a scannable QR code.
