NFC is getting a great deal of attention as it
becomes included in more smartphone, laptop, tablet, and
other device. It's being hyped as The Next Big Thing that will change how we
use our mobile devices: everything from shopping to interacting with your home
and unlocking your car. Here's an overview of the current and potential uses of
NFC.
NFC in a Nutshell
NFC
stands for Near Field Communication, and, as the name implies, it's a set of
close-range wireless communication standards. NFC-equipped smartphones and
other devices can exchange information with each other with a simple tap or
wave.
Remind
you of tap-to-pay credit cards or apps like Paypal "bumping" to
transfer money? That's because NFC is the technology behind many new mobile
payments types such as these.
NFC
and RFID (radio frequency identification) are sometimes used interchangeably,
but NFC is really a newer version or extension of RFID. RFID waves can have
very long ranges (e.g., RFID is the tech that helps highway toll readers read
your car's toll pass), while NFC limits the range of communication to within 4
inches. This makes NFC perfect for more secure applications like paying for
things or securely logging in at a location.
NFC
also allows two-way communication, as opposed to RFID's one-way reading
technology. So transferring photos or contacts between devices is a common use
of NFC (see the "Android Beam" feature on many new smartphones).
Which Devices Have NFC?
Many
smartphones and new laptops have NFC chips. NFC World has an exhaustive list of
all the phones around the world that are NFC-equipped (available now, coming
soon, with limited availability, and more categories). Google Nexus variants
have NFC, as do several BlackBerries, HTC phones, and others. NFC chips are
also embedded in "tags," which are stickers that your device can
interact with.
Among
the phones without NFC: The recently announced iPhone 5,
despite previous rumors. Apparently, Apple thinks its Passbook feature is
enough and people don't need NFC.
Devices
that supports NFC:
BlackBerry
Bold 9790, BlackBerry Bold 9900, BlackBerry Bold 9930, BlackBerry Curve 9350, BlackBerry
Curve 9360, BlackBerry Curve 9370, BlackBerry Curve 9380, Samsung Galaxy Nexus,
Google Nexus 7, Google Nexus S, HTC Desire C, HTC Droid Incredible 4G LTE, HTC
Evo 4G LTE, HTC Incredible, HTC One X, HTC Ruby, Motorola Droid Razr, Motorola
MC75A HF, Motorola Photon Q 4G LTE, Nokia 603, Nokia 700, Nokia 701, Nokia 801T,
Nokia 808 Pureview, etc. (Read more here)
What You Can Do With NFC
NFC
is most commonly associated with the "mobile wallet"—the idea that
your smartphone will replace your cash and credit cards. In one tap or wave of
your phone, you can pay for your groceries and redeem offers or coupons. Google
Wallet, partnering with MasterCard PayPass, is one example. You can store all
major credit and debit cards in Google Wallet and get a "virtual
MasterCard" that pays for your purchases in-store wherever those PayPass
scanners are or online.
At
the Intel Developer Forum (IDF) this week in San Francisco, Intel showed off
the interaction between a smartphone and an Ultrabook laptop. The phone, tapped
to the laptop, logged into a site and paid for an online purchase—no
form-filling required.
Beyond mobile
payments, though, there are a world of uses for NFC, including:
● Paying for your
parking meter, at least in some cities like San Francisco.
Getting tickets
or boarding passes. Some airlines and buses are also experimenting with using
NFC for boarding passes
● Opening doors.
BMW has NFC-enabled car keys. Companies and universities are looking into or
rolling out using NFC-enabled devices as security badges. To gain physical
access somewhere, members need only tap their smartphones at the door.
● Downloading
information. Advertisers and marketers can use NFC chips in porters and other
promotional materials so all you have to do to get more information is tap or
wave your phone (easier than QR codes, perhaps).
