QR Codes are as secure as the data that you save in them.
If you create a Static QR Code, your data will be hard-coded directly into the QR Code and will not have any connection with the service provider. Note that Static QR Codes are non-editable and non-trackable.
Whereas, if you create a Dynamic QR Code, service provider's short URL is hard-coded into the QR Code and your data gets saved on service provider's servers. To know about the security measures Scanova follows, see this link.
