Do you still have a mobile phone in your hotel? Don't be too happy, the phone is not white for tourists, but the key to your stay in the hotel room. Now when you travel to Switzerland, you can experience this service in a restaurant in Stockholm, Sweden.
A hotel in Stockholm, Sweden, plans to use a mobile phone instead of a key or a door card to open the door for a four-month trial period. Assa Abloy AB, the world's largest manufacturer of locks, used the near-field communication technology to develop this “phone key†and put it into trial at the Clarion Hotel in Stockholm.
This hotel will issue a mobile phone to each customer as a key. A close-range radio frequency chip is placed in the mobile phone so that guests can check in via mobile phone before arriving at the hotel. As for opening the door, just let the phone close to the door lock.
