Device identification number

[alessia_perta]

Hi! Is there any possibility to have an identification number of the device where the questionnaires has been filled?
I ask this because in my research study people have filled in two different forms, and I would like to know if I can match the compilation data of the same person.

Welcome to the community, @alessia_perta! Maybe this post discussed previously should help you solve your issue:

Is there a way to know the device which collected the data for the following _id?

Welcome back to the community, @musto! This is possible if you activate the device id metadata from under the Layout & Settings of that particular survey project, as shown in the image below: [image] By doing so, you will be able to see the same as follows: [Image 1] But also please note that this will now be able to show you the details for those data already collected and stored in your server. It will only work for those collecting after the configuration is done.
