                                answer="No. Static URL QR codes do not expire. They contain the direct link to your website. As long as your website is active, the QR code will work."

                                answer="No, static QR codes cannot be tracked. If you need analytics to see who is scanning your code and from where, you need a Dynamic QR Code."

                                answer="If you change your URL, this static QR code will no longer work (unless you set up a redirect on your own server). With a Dynamic QR Code, you can update the destination URL anytime without reprinting the code."
