I hadn’t thought about this much when I ordered my xM1, most hotels use battery powered readers. As hotel keys are my main use case for the xM1. Now this is an option maybe I should just skip the xM1 and get a flex instead.
Or I could just use both, but if I have a use case for 2 may as well get 2 flex.
On that note, is there anything that would technically stop the apex acting as a mifare classic 1k?
