Static QR codes are permanent. Static QR codes are created once, and their information cannot be changed. If the information embedded within a static QR code is still valid and functioning, it will continue to work consistently whenever it is scanned. Similarly, dynamic QR codes are also permanent. However, if the payment deadline for dynamic QR codes expires and no payment is made, the QR codes will become deactivated. They will be reactivated once payment is made again and continue to function permanently.
