You go down to the front desk and get a key for your room. This isn't like a phone is the only way in a room. It's not a one-fits-all solution for everyone. It's for people that have Starwood Accounts linked on their compatible smart phone that have no desire to stand at a Check-In-Desk. As far as the key itself, they could very well even have a hard keyhole on the door (Like Disney does) or just have RFID enabled locks as well or even (Not sure why they would want to) keep the old mag stripe system. It's not that hard of a concept to understand, it's actually pretty simple and effective.
Magstripe readers have wear problems, Remember a magstripe is Magnetic Iron Oxide ie RUST it's somewhat abrasive and read heads simply wear out, RFID systems do not have mechanical wear problems.
