question about quick share

we start using quick share wit the QR code for contactless sign in

but every time a person sign in after a period of time sign in again without filling up the form again

my guess is that stays in their browsers background on the phone or tablet and refresh the form automatically and sign in the person again without the person actually do it

it is anyway that the form can be used for that person just once?

Or the thank you page just bounce back after finish to start page so it wont refresh the sign in duplicating it?

thank you

Thank you for reaching support,

You may set up UNIQUE Submissions on the form that way, users can only submit once.

Here is the related guide: https://www.jotform.com/help/64-how-to-set-unique-submissions-on-a-form.

You may also set the Allow browser AutoCOMPLETE to NO, that way, info saved on the browser won't be reapplied:

I hope that helps.

Best.
