About QR Codes

QR codes encode data in a two-dimensional barcode that any smartphone camera can scan. They're used for everything — linking to websites, sharing WiFi credentials, encoding contact info, and mobile payments.

What You Can Encode

• URLs — Link to any webpage. The scanner opens it directly in the browser
• WiFi — Encode network name, password, and encryption type. Scan to connect instantly — no typing
• Email — Pre-fill the recipient, subject, and body of an email
• Phone — Encode a phone number for one-tap calling
• Plain text — Any arbitrary text up to about 4,000 characters

Tips for Better QR Codes

Keep the encoded data short — longer data means a denser pattern that's harder to scan from a distance. For URLs, use a short link if the original is very long. Always test your QR code with an actual phone camera before printing or sharing it.
