A static QR code is when data is directly encoded into the QR code itself and cannot be changed without making a new QR code. You do not need to have Internet access in order to extract information that is encoded in a QR code (if a web link or an email address is encoded, then the device will receive information about what kind of link is encoded. But to go to the link or send an email, it will be necessary to connect to the Internet).
A dynamic QR code is a QR code that only contains a link to the content management page. By and large, it is a kind of static QR code with a link to a web page. Data that is displayed when scanning a dynamic QR code can be changed without the need to alter the QR code itself. When you scan this QR code in order to extract information, it is necessary to be connected to the Internet.
