Häufig gestellte Fragen
What error correction level should I use?
L (7%) for clean digital displays, M (15%) for most print uses, Q (25%) if part of the code may be covered, H (30%) if you want to overlay a logo.
What's the maximum content length?
QR codes handle up to ~2900 alphanumeric characters, but shorter URLs scan faster and more reliably.
