QR Content Formats Explained

URLs are the most popular payload, but you can encode a variety of actionable data:

mailto links, phone numbers, SMS templates, geo coordinates, calendar events, and more.

For Wi‑Fi, the standard format is WIFI:S:<SSID>;T:<WPA|WEP|nopass>;P:<password>;;.

For vCards, keep field counts conservative to avoid exceeding version limits.
