Hi,
In two of my recent studies, I found two subjects having the same subject id/confirmation code. Most likely its the same subject repeating the study, as the other demographic info is the same.
I was wondering that if someone clicks the link twice, won't they be given a unique id/confirmation code each time? Is there a way to avoid duplicate ids? (I used sequential confirmation code generation); If I use random generation will it solve ?).
Thanks.
