hi friends many of us have heard about NFC technology while roaming around the globe, but some of them (including me) may are not familiar with this term…so let’s see what is NFC ? and its use in Smartphone applications.
What Is NFC?
Near field communication, or NFC, allows for simplified transactions, data exchange, and wireless connections between two devices in proximity to each other, usually by no more than a few centimeters.
Emerging NFC standards allow users to transfer information by touching devices like smartphones, apples, Samsung Galaxy and many more.
It is expected to become a widely used system for making payments by smartphone in the United States.
Many smartphones currently on the market already contain embedded NFC chips that can send encrypted data a short distance (“near field”) to a reader located, for instance, next to a retail cash register.
Shoppers who have their credit card information stored in their NFC smartphones can pay for purchases by waving their smartphones near or tapping them on the reader, rather than using the actual credit card.
Co-invented by NXP Semiconductors and Sony in 2002, NFC technology is being added to a growing number of mobile handsets to enable mobile payments, as well as many other applications.
Uses of NFC technology in android phones in daily life:
The followings are the common uses of NFC in our daily routine.
NFC and social sharing:
NFC simplifies and expands social networking options:
- File-Sharing: Tap one NFC device to another to instantly share a contact, photo, song, application, video, or website link.
- Electronic business card: Tap one NFC device to another to instantly share electronic business cards or resumes.
- Electronic money: To pay a friend, you could tap the devices and enter the amount of the payment.
- Mobile gaming: Tap one NFC device to another to enter a multiplayer game.
- Friend-to-friend: You could touch NFC devices together to Facebook friends with each other or share a resume or to “check-in” at a location.
Bluetooth and WiFi Connection:
NFC can be used to initiate higher speed wireless connections for expanded content sharing.
- Bluetooth: Instant Bluetooth Pairing can save searching, waiting, and entering codes. Touch the NFC devices together for instant pairing
- WiFi: Instant WiFi Configuration can configure a device to a WiFi network automatically. Tap an NFC device to an NFC enabled router.
NFC expands eCommerce opportunities, increases transaction speed, and accuracy while reducing staffing requirements. A Personal identification number (PIN) is usually only required for payments over $100 (in Australia) and £15 (in the UK).
- Mobile payment: An NFC device may make a payment like a credit card by touching a payment terminal at checkout or a vending machine when a PIN is entered.
- PayPal: PayPal may start a commercial NFC service in the second half of 2011.
- Google Wallet is an Android app that stores virtual versions of your credit cards for use at checkout when a PIN is used.
- Ticketing: Tap an NFC device to purchase rail, metro, airline, movie, concert, or event tickets. A PIN is required.
- Boarding pass: A NFC device may act as a boarding pass, reducing check-in delays and staffing requirements.
- Point of Sale: Tap a SmartPoster tag to see information, listen to an audio clip, watch a video, or see a movie trailer.
- Coupons: Tapping an NFC tag on a retail display or SmartPoster may give the user a coupon for the product.
- Tour guide: Tap a passive NFC tag for information or an audio or video presentation at a museum, monument, or retail display (much like a QR Code).
So from the above-detailed introduction about NFC, the time will come when every industry of smartphones will be occupied by this way of Communication.
