よくある質問
What can I encode in a QR code?+
Nearly anything: URLs, plain text, WiFi network credentials, email addresses, phone numbers, vCard contact info, calendar events, and more.
Do QR codes expire?+
Static QR codes (like those generated by this tool) never expire. The code is simply an encoded representation of your data. As long as the encoded URL or content remains valid, the QR code works forever.
What is error correction in QR codes?+
Error correction allows a QR code to be read even if part of it is damaged or obscured. Higher levels (H) allow up to 30% damage tolerance but produce denser codes. Lower levels (L) allow 7% tolerance but are simpler to scan.
