NFC

Though it's increasingly less certain that near field communication (NFC) will appear in the iPhone 5, it's a technology that's built into a lot of high-profile products already. So, what is it exactly? And how relevant is it today?

What is NFC? NFC is a short-range wireless connectivity technology that uses magnetic-field induction to enable communication between electronic devices in close proximity. (Faraday's law: any change in the magnetic environment of a coil of wire will cause a voltage to be induced in the coil.)

NFC can operate in three modes, according to an NFC whitepaper: … Read more

Will the iPhone 5 support mobile payments via NFC? A report out yesterday from the folks at AnandTech says no.

Alleged photos of the iPhone 5's assembly posted by Taiwan-based blog Apple.pro pointed to a part that not seen in previous photos. The dimensions of the part reportedly matched those of certain NFC chips, leading to speculation that the mystery component could be an NFC chip.

The addition of electronic ticket organizer Passbook to iOS 6 also fueled rumors that the new iPhone would let users make mobile payments using near-field communications.

But AnandTech has discounted both of … Read more

Apple has won a patent that adds another piece to the puzzle of mobile payments via near-field communications.

Dubbed "Motion based payment confirmation," the new patent details several ways to help the user confirm that a mobile transaction has actually been completed while using a mobile device like an iPhone or iPod.

One method points to a graphical element on the screen that the user can move to confirm or decline a transaction. Another method cites the use of an accelerometer to sense movement of the device and move the graphical element in response.

The iPhone 5 will sport the usual home button, front camera, and a currently unidentified component that could be an NFC chip, according to AppleInsider.

Scouring photos posted by Taiwan-based blog Apple.pro (English translation), AppleInsider discovered a part that had not appeared in previous photos. The size of the part has lead to speculation that it could be a chip for near-field communication, or NFC.

Positioned next to the front camera, the square part matches the size of other NFC chips, such as the one made by NXP, AppleInsider noted. Of course, the photos by themselves don't prove … Read more

Hate thumbing e-mails on your phone? Japan's Elecom is launching One2Touch's portable keyboard that connects with your handset via near field communication (NFC). When you don't need it, just fold it up and slip it into your pocket.

Announced earlier this year, the silicone rubber accessory is billed as the word's first full-size keyboard for smartphones that does without cables, pairing, and battery charging; the internal battery lasts about 18 months. … Read more

One of the many drawbacks to using Google Wallet as a true wallet replacement was the inability to add a Visa, American Express, or Discover card as a payment option. You were either limited to using a prepaid card Google provided you with, adding money to it each time you wanted to use it. Or, you had to own a MasterCard.

But, with the update Google just released, users can now add any debit or credit card to their Google Wallet account, and use it to make purchases with their NFC equipped Android device.

The update takes all of the … Read more

InstaWifi lets you share access to your wireless connection by using NFC tags or a generated QR code. This is a great tool for business owners who have customers or office guests who want to connect to their wireless connection. It's definitely a faster option than giving them a password to type in, or keeping said password written down with the potential of getting lost.

If you need a quick recap on how to create NFC tags, check out Jason Cipriani's How to program an NFC tag with your Android device before you get started. The … Read more

Heads up, Google. Apple may be eyeing its own "portable heads-up display" that could one day give Google Glass devices some competition.

Outlined in a filing published by the U.S. Patent and Trade Office yesterday, Apple's patent application refers to a technology that increases the resolution on a display without increasing the number of pixels. Such technology could be used in a portable heads-up display, Apple explained, where limiting the number of pixels is especially useful.

"In particular, a portable heads-up display may be size and weight constrained such that addition of physical pixels may … Read more

LAS VEGAS -- Security specialist Charlie Miller demonstrated at the Black Hat security conference today a way to hijack an Android smartphone via the Near Field Communication (NFC) technology that's turned on by default on the device, and said he's found problems with NFC implementations on Nokia as well.

NFC tags have built-in antennas and are found in stickers and smart cards that are designed to transfer data to NFC readers, to send specific phone numbers and Web addresses to smartphones and other benign purposes. They require close proximity, a few centimeters or so, for data to be … Read more
