Earlier, we talked about how ordinary users can use NFC securely. However, truly widespread adaptation of NFC is only going to happen if businesses adopt it for their own use. How can businesses safely use NFC for their own purposes?
For one of the most popular uses of NFC – mobile payments – businesses really aren’t in a position to use their own solution; what’s more likely is that businesses will adapt some sort of existing mobile payment system. Both credit card and mobile providers are trying to enter this space, but both groups will support NFC. In such a situation, what businesses can do is ensure that their solution is from a reputable vendor, and to keep themselves informed about any potential security loopholes in the solution they adopt.
However, payment systems are far from the only use of NFC in businesses. At the simple end, it can be something like letting people visit a website without typing a URL or scanning a QR code. However, as the standard develops, something like this becomes possible: a shop wants to offer free WiFi to its customers, but doesn’t necessarily want to expose it to the entire world. What they can do is put an NFC tag at the entrance that customers entering can swipe to set their phone’s WiFi settings.
NFC tags could also be used to automatically update someone’s social media – it’s easy to imagine a tag for Twitter, another for Facebook, and another for Foursquare (just to cite three popular social networks that one might be interested in using on the go). All of this can be done either now, or are quite likely to become possible in the near future.
