SMS opens public toilets in Finland

To unlock the door of one of the roadside toilets along Finland's freeway system, you'll now have to send it a text message with your mobile phone.
The toilets have been secured, and a sign outside explains that the user just sends the word "open" (in Finish) to a short code and the door will be unlocked remotely. The company managing the service will keep a short term record of all users phone numbers, simply so that if the toilet is then damaged by criminals, they can be traced by the police.
