Frequently Asked Questions
No. Static QR codes embed the destination URL directly into the QR pattern. Once printed, the pattern is physically fixed and cannot be changed or redirected.
Static QR codes are suitable for permanent links that will never change, such as plain text, email addresses, phone numbers, or Wi-Fi login details.
QR Zam's dynamic QR codes remain active as long as your account is in good standing. Free accounts have certain scan limits, but our paid plans support high or custom scan volume limits.
A static QR code encodes the entire target URL. Long URLs generate more rows/columns of pixels, making the pattern dense and harder for camera sensors to decode, especially in low light or at small print sizes.
