>X-QR is a QR code generator, a tool that helps you create your own QR code quickly and easily. Once youve finished creating your QR code, you can upload it and paste it into your website, landing page, or email campaign. In addition, you can print it and put it on public display. Can a QR code expire? As long as the data that you encrypted using the QR code is up-to-date, it will also be up-to-date.<
