Rather have a bar code scanner. Front desk sends you the image and you forward it to anyone who needs a key. Probably cheaper to install and maintain. Works with any network. Also, anyone who gets a hold of your phone, probably could get your keycard too. They still have to figure out the room number in any case.
"If an experiment by the Holiday Inn spreads to other hotels, we may find ourselves living in a world where all you need to open your door is your mobile phone."
All I ever needed to open my room door is a little 15 cent plastic card, certainly did not seem like that big of a deal to me.

Actually, not so at all. The connection will most likely be encrypted, and "that signal" would only work once, in a handshake context. The idea is not bad at all, probably someday all your keys, money, IDs etc. will pe stored on some electronic device, be it smartphone or something else. The biggest problem wouldn't be security, but simply making all the checkpoints and devices that can read the stuff everywhere. So prolly still 20-30 years away.
I've never lost my card, I just put it in my wallet after I open the door. I'd rather the cost of the room not go up for something I won't use. What if my battery on my phone dies, then I'll just have to go and get some one to open the door for me. I have had my phone die on my more than I've lost a key or a key card.
[citation][nom]Solarium[/nom]You do know that now your phone is your room card you're going to lose it? It doesn't matter what form the room card takes, you're destined to lose it[/citation]Exactly. If they decided to have our room keys take the form of Volkswagen-sized rocks, we would still lose them.
