The mobile phones which were mainly created for communication purposes have now turned to become something much more than just used for communication.
The phones can also be used as a key to unlock doors at a hotel in Sweden. The technology which is developed by
Assa Abloy AB which is also the Worlds largest manufacturer of doors locks has started a project at the Clarion Hotels at Stockholm,Sweden which uses some radio chips inside the phone. The short-range radio technology, known as Near Field Communication, is expected to be built into smart phones in the coming years.ssa Abloy says it wanted to test the system before expanding it to other hotels, commercial buildings and homes.
The head of Assa Abloy’s mobile keys division, Daniel Berg, acknowledged that participants in the trial may find it cumbersome to have an extra mobile phone.
