I did a project several years ago for mgm that involved BT, player cards, key systems, wifi, etc and I can confirm they hotel locks are controlled centrally for various reasons.
- willcipriano 3y agoI would've thought it would get sent messages like: <Grant access to KEY_ID> <Revoke access from KEY_ID> And it would keep track internally so that if the central system went down it could still function with already issued keys until it is fixed.
- TylerE 3y agoSuch a system seems like it would be incredibly fragile to local attack - and this is one case where you can't just assume "physical access means you've already lost".
- willcipriano 3y ago> physical access means you've already lost I agree, thats why I figured if you can get away with fooling around with a lock, some wires and a laptop in the hallway, you can probably pick the backup key more discreetly.
