If you have added a document either to the event or as a required document then each visitor will need to agree to and sign the document at the time of check-in.
If a signature tablet is being used then the document can be digitally signed, otherwise it can be printed out to be physically signed.
Once the document has been either signed or printed, you can click on finish to complete the check-in.
All digitally signed documents are stored in the following location by default:
C:\Users\Public\Documents\VisitorExchange\Documents\
