Surprised to Learn Any Card Can Power a Hotel Room – Was I the Only One Who Didn’t Know?

We were staying in hotel at weekend and they were short off cards , and they actually told us to do it , I didn't know either.
 
How did I not know this? Trying this next time, I'll be very impressed if it works? Does housekeeping not remove it though?
 
Found out by accident a few years ago, ideal when abroad to leave Air con on, never had ours removed, although I imagine that may change due to cost of living lol xx
