Creating a warning sign if the same QR/barcode is scanned twice by 2 different people


I work in a NGO and I will use 3000 barcodes to register the beneficiaries on kobo
is it possible to allow the barcode to be used just one time ?
I mean can we prevent 2 people to open the kobo registering form using one barcode ?

@Diana639, having a unique case (submission) within the server database is impossible. We, however, have a feature request for it. Maybe you could VOTE for the same to make it a reality in the near future.

Note: If you have funding available for this feature, please feel free to reach us so that KoboToolbox could review this feature request to get to a priority.
