This document reflects the work that has been carried out in the project the last nine months, in which two of the today’s most emergent technologies have been combined: Near Field Communication (NFC) and the social networks. The project appeared from the will of the companies where the project has been carried out (IHG and nfc studio) of making a demonstration in the Mobile World Congress 2009 of a tool that allowed the combination of the two technologies quoted before. This demonstration was performed in the stand of the company NXP. On one hand, the very short distance data transmission technology NFC has been used. This technology is already implemented to perform payments using the mobile telephone in public transport in many cities from all over the world, and a pilot test has already made in the Barcelona underground. On the other hand, the social networks, and especially Facebook and Twitter, are becoming more important in our societies. If few months back they were only an additional way to be in touch with our friends, in the present they are an indispensable tool of communication: the great brands have their spaces there, the radio and television channels use them to provide interactivity to the programmes, and even some governments they have opened a new communication channel with the citizens using the social networks. The result of the project is a system that allows, from the ease of use that provides NFC technology, to be able to send information to Twitter and Facebook avoiding the need to type the text by hand. When approaching the mobile phone to an information point, an application will be launched and will send a SMS to the social network to update the user status. Besides, two additional functionalities have also been added: being able to know the song that is playing on any of the iCatFM radio channels and being able to issue a vote using the mobile telephone.
