FYI
I generally stay at Rydges Southbank when I’m in Brisbane, Pretty sure they use Mifare Ultralight.
I just got back from Christchurch yesterday and stayed at Rydges, which also use Mifare Ultralight.
We did start keeping a list of hotels and hotel chains and what they use, but we havent maintained it. (I should reinvigorate it)
