Visitors to a Stockholm hotel will be able to use mobile phones instead of keys to unlock the doors to their rooms. Unlike the trial in the US I mentioned in September, this requires NFC which few phone manufacturers other than Nokia have public plans to implement.

Assa Abloy AB, the world's largest maker of door locks, has launched a pilot in which Clarion Hotel Stockholm will lend customers mobile phones with close-range radio chips, much like devices used for contact-less payments at gas stations.

Repeat visitors during a four-month trial will be able to check in through their phones before arrival and have their phones activated as "keys." They will then be able to skip the registration desk and unlock the door by holding the phone next to it.
