Unfortunately, you can not prevent multiple submissions from users via the QR reader.
In order to have unique submissions, here are the options available:

2. You can also use our unique question feature to prevent from submitting duplicate submissions. Example: You can set one of your forms question (like cell number or email address) to be a unique question. This will not allow a user to use the same cell number or email address to submit your form. Here is a guide:
