At the start of the year, we reported on a number of Sony Xperia smartphones and accessories supporting NFC (Near
Field Communication). In that article, we also looked at NFC technology
in more detail, provided some use cases, and explained how we work with
NFC. And in that time, we’ve introduced even more NFC-supported
smartphones. Read on to get the full list and a general recap of what
NFC is all about.
The beginning of 2012 marks an important milestone for us, because that’s when we introduced theXperia S and Xperia ion, the first Xperia™ devices supporting NFC. We also unveiled Xperia SmartTags,
which are SmartExtras accessories that can launch a number of
pre-configured profiles in the phone. Since then, the number of
NFC-supported Xperia™ smartphones has grown, and the list now includes:
What is NFC?
Near Field Communication, or NFC, is a technology that enables data
exchange between devices within a short distance, typically only a few
centimetres. In most cases, the communication takes place between an
active device and a non-powered target, but peer-to-peer interaction
between two powered devices is also possible. Transfer rates are low,
ranging from 106 Kbit/s to 424 Kbit/s, which means that use cases are
all about small data exchanges. A typical use case would be to use the
NFC connection as a trigger to set up Bluetooth™ or Wi-Fi™ connections.
NFC can be separated into three different technical modes which suit
different use cases: reader/writer mode, peer-to-peer mode and card
emulation mode. When developing your own NFC-enabled app, you will find
out that the different modes all cater to different needs. These modes
are introduced and explained on the NFC technology page. And if you’re interested in developing an app that uses NFC, you’ll find the information you need in the Android SDK to
get started with NFC in your own apps. And stay tuned to Developer
World for an update on what we’ll be doing with NFC in the coming year.
