What's the maximum text length supported?

Up to the highest QR version's capacity — thousands of characters — depending on the error correction level chosen.

What does error correction level do?

Higher levels (Q, H) let the QR code stay scannable even if part of it is damaged or obscured, at the cost of density.

Can I use this for WiFi or vCards?

Yes, paste the appropriately formatted string (e.g. WIFI:T:WPA;S:name;P:pass;;) as the content.
