Ashley,
I can see what you're trying to accomplish by having a visual attendance report. Another option which other churches are doing is to run an Attendance Roster report such as the M1025 about 15-20 minutes after the service has started. This would show exactly who is in attendance. These can be passed out to each room. If anyone comes into the room after the report is executed, they can be added to the bottom of the report. This is being done not only churches that are doing Self Check-In, but also churches using the Assisted Check-In.
I'd recommend that you post this idea of printing X number of name tags for Self Check-In in the IDEAS section of the Experience website. You'll first want to see if anyone else had the idea and praise it. You can also comment on their ideas as well.
Blessings,
