You can add and delete tags on your kiosk (right from the kiosk) at any time by simply following the steps below:
1) Click on the AirLoop icon on the bottom right of your kiosk 4 times in rapid succession
2) Choose "Yes, End Kiosk Mode"
3) Tap on your Channel that shows under "Select Channel" and select "Kiosk Check-in Tags"
4) Click on "Add New" on the top right hand corner of the new window
5) You can enter as many tags as you want in the "New Tag" box, making sure that individual tags are separated by commas
6) Click on "Done" on the top left hand corner
7) Again tap on your Channel that shows under "Select Channel" and select "Launch Kiosk"
Your tags are now set. Do remember though to delete your tags when you do not want your customer check-ins to be tagged any more.
