Thank you for your post.
This action would be similar to another machine using FileMaker Pro dedicated for this type of activity.
Look at Account settings to create an account that has limited access. This would allow a user access one layout.
One possibility is to create a layout with global storage fields, and when a button is pressed, a script is run to validate the data and then upload the information into the main table. Once finished, it returns to the layout and blanks out the global storage data for the next person to add his/her information.
In addition, you can use Get (SystemPlatform) to determine the machine they are running. A "3" is returned for iPad/iPhone devices. You can also use Get (SystemVersion), as this displays either a 3.2.1 or 4.0 for the iPad/iPhone devices.
Let me know if you need additional clarification
