Is this in a hotel? I suppose that's technically true. It's not like they have to give you a room key. Also, people lose them and they get demagnetized and stuff. I've had to replace mine more than once. So maybe that's what they mean?

I'm trying to be as generous as I can because I really don't want it to mean something worse.

I mean; digital access control isn't all that new. The entrances to my apartment building uses RFID tags, so tags(keys) can be added/removed easily without modifying the physical lock.

This is more or less the same thing, just expanded to use the RFID/near-field built into most mobile phones as well as physical cards/tags. I guess the 'service' part would be the addition of cloud services + apps to make remote monitoring/config/user management easier?

Not the kinda thing I like having in a third parties control, or dependant on internet...
