Is there a widget for checking my registrants in at the event?

I'm thinking of someway we can pull up there record see theri details and or mark that they were there using an Ipad. Or could I import data into another type of form than I used for registering and do something that way? Anybody have a suggestion. Thanks!

You could add a field to your form to note whether or not that person was at the event. This field could be added to an admin section of the form.  Here is a guide on how to setup a password protected section of a form:

If you do go this route, take care not to use the term "password" in your form.  Use something like "Admin".  Using the word password in a form will result in that account being suspended.

You could use the submission view to manage the submissions.  There is a search bar at the bottom.  When someone arrives, search for they name to bring up their submission:

Edit the submission to include whether or not that person was there.
