Anthem Bagage Tags

I have read on several Quantum reviews that people had their check in bags tagged at the pier.

Are self printed Bagage Tags no longer in use for our Anthem maiden voyage cruise?

They're put on at the pier because they're now RFID so you can track the luggage on your Royal IQ app which you can download before you go but it only works when connected to the ships wifi

That makes sense. So do you put on temporary tags before arriving which they use to identify which tag to apply to your case, or do you just leave your cases 'naked' and they use your SetSail pass (or whatever it's called) to identify the correct tag?

I'm booked at Anthem April 30 and has access to print the luggage tags from the 'Online Check-in' status page. Also a printable luggage tag as part of the 'Guest Vacation Document'.
