Near Field Communications (NFC) is a form of wireless technology that allows users to receive or share information at short ranges of typically 4cm or less. NFC devices can also communicate with RFID (Radio Frequency Identification) tags. It is a technology that has been developed especially to work with mobile phones.
The development of NFC-enabled mobile phones such as the Google Nexus S, has led to the possibility of using a phone as a digital wallet for contactless payment such as that offered by Visa’s Paywave or the
London transport system’s Oyster Card.
NFC technology allows the sharing of information between two NFC mobile devices once they are in close proximity, in a similar way to the way Bluetooth operates, but in a much faster and more convenient way.
In order for two NFC mobile devices to connect, they need only to be within range of each other. Both users confirm the operation, and information may be transferred between the two units.
This can allow users to transfer items such as store vouchers between two “digital wallets” but could also have a transforming impact on the way we engage in social networking.
Two years ago, researchers from the Chair for Information Systems at Technische Universität München developed a prototype application called NFriendConnector which allowed NFC-enabled phones to interact with Facebook.
The prototype, which was submitted to the NFC Forum’s, Global Competition in 2009, came from a desire to, “Use Near Field Communications to map your social life much more easily to your online social life on Facebook,” according to the Munich University’s Philip Koene.
His colleague Felix Köbler notes that, “Just using Facebook or any other social network and sitting in front of a PC device will not be the future.”
He continues, “In the past when people came together in virtual communities in precursors to the social networks of today, people connected online and then transferred their social relationships from online to offline. Now it is basically vice-versa. People map their real social relationships into facebook, so we think that any application that is enabling or even supporting this process is of great help to people.”
The application allows users to swipe their phones alongside each other and download each other’s Facebook profiles to be browsed at a later time. It also contains a function that will match user’s profiles, and generate automated status updates.
“All you have to do is touch the cell phone of the other person and you can make a new friend connection, or you can make a new status message that tells your community on facebook that you have now met this other person. We thought it would be a kind of neat way to map your real life on to your online social networking,” says Philip.
He explains that, “The broad idea was that you kind of have data, for example, that you met this other person in real life, that you’re at a specific location in real life. You can gather this data quite easily because you just have to touch something with your telephone, that’s all that’s basically needed. And then you have an app like NFriendConnector where you can map this data easily on to your social network.”
The application is not available at the moment as it was, “Used from a research perspective actually,” says Felix. “The prototype is basically two years old now so that’s quite a long time when the markets are being filled with applications.
“NFriendConnector was developed in a University setting so with developing it, doing research with it and then publishing it; a lot of stuff happened in that time.”
Philip notes that the speed with which mobile technology is developing also presented a problem, “We developed the NFriendConnector for the Nokia NFC-enabled cell phone of the time which was rather a low key device compared to today’s smart phones.”
A version of the app which translates its features to the Google Nexus S phone is in development. “We don’t have a title, just a working title right now. We hope to bring it onto the Android marketplace when it’s finished just to evaluate it when it’s finished, maybe in a few months,” says Philip.
“What we saw is that people see payment as the big application for NFC, but through our presentations we met other people who see social networking as another possible driver for NFC,” notes Felix.
Philip explains why he his optimistic as to the future of NFC-enable social networking thus, “The whole touch metaphor is extremely simple. If you set the application up right, the user won’t have to do anything else other than touch something and that will then be mapped onto a whole range of social networking sites.”
“It kind of had a slow start, but we believe it’s coming. NFC enables, in my opinion, a very natural interaction with your mobile phone. You just have to touch something with it to start an interaction.”
“The guys from industry always tell us that it’s coming and that this will be the year of NFC. NFC really has a lot of potential and we’re hoping that it’s coming to a bigger market and that we can do broader research with it.”
