As discussed in the previous post about the choices which you will need to make about attendee check-in flow and hardware used, you'll the most probably want to have one or more human-operated registration desks for all attendees who, for some reason, are not able to use self-service check-in kiosks. The badges issued at those registration desks should, of course, have the same touch and feel as the badges issued at the check-in kiosk. However, you don't have to use the same printers, and you will often want to opt for a hybrid solution.
Imagine the following situation: you have a main group of attendees, let's say "regular attendees," which covers 90% of your total attendees. These are primarily who you're targeting with self-service check-in, allowing you to choose budget-friendly thermal printers for these kiosks.
But, what to do with the remaining 10% of your attendees? They are exhibitors, speakers, VIP guests, or other groups of people for whom you'd like to provide badges in different colors and designs. Plus, there will also be regular attendees who will not be able to check-in at the self-service kiosks for various reasons - they will also seek help at the registration desk.
