From Wikipedia, Near Field Communications...

Near Field Communications (NFC) standards began in 2004 to enable simplified transactions, data exchange, and connections with a touch. A device with an NFC chip could make a payment or serve as a keycard. NFC devices can read NFC tags on a museum or retail display to get more information or an audio or video presentation. NFC can share a contact, photo, song, application, or video or pair Bluetooth devices. The 140 NFC Forum members include LG, Nokia, HTC, Motorola, NEC, RIM, Samsung, Sony Ericsson, Toshiba, AT&T, Sprint, Rogers, SK, Google, Microsoft, PayPal, Visa, Mastercard, American Express, Intel, TI, Qualcomm, and NXP.

Social networking
• 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 friend each other or share a resume or to "check-in" at a location.

Bluetooth and WiFi Connections
• Bluetooth: Instant Bluetooth Pairing can save searching, waiting, and entering codes. Touch the NFC enabled devices together to pair.
• WiFi: Instant WiFi Configuration configure a device to a WiFi network. Tap an NFC device to an NFC enabled router.

• Mobile payment: An NFC device could make a payment like a credit or debit card by touching a payment terminal at checkout or a vending machine.
• PayPal: PayPal may start a commercial NFC service in the second half of 2011.
• Ticketing: Tap an NFC device to purchase rail, metro, airline, movie, concert, or event tickets.
• Boarding pass: A NFC device may act as a boarding pass reducing check-in delays and staffing requirements.
• Point of Sale: Tap an 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).

Identity documents
• ID card: An NFC enabled device can also act as an encrypted student, employee, or personal ID card or medical ID card.
• Keycard: A NFC enabled device may serve as car, house, and office keys.
• Rental Car and hotel keys: NFC rental car or hotel room keys may allow fast VIP check-in and reduce staffing requirements.

In May, 2009 the NFC released NFC Peer-to-Peer Standards to transfer contact, website URL, or pair Bluetooth devices nearly instantaneously for apps like multi-player gaming. Today, apps such as Electronic Pickpocket, NFC Reader, NXP Tag Writer, or NXP TagInfo can use the NFC chips in phones such as the Nexus S (12/06/10) or Samsung Galaxy S II. Many apps can read the RFID chips in credit cards.

The free iPhone and Android Bump app is similar to peer-to-peer NFC in that it can transfer contacts, songs, messages, photos, events, money, friends, and apps between devices. QR-Codes are similar to NFC tags in that up to 4,200 characters can be read with apps like Barcode Scanner.

How to NFC
Nick Pelly, Jeff Hamilton - notes from Google I/O 2011 - 05/11/2011
(Time) is given to show location in the video.
• (3:00) Near Field Communications
• Short range wireless, Low Speed, Low friction setup (no discovery, no pairing)
• Passive targets (look ma', no batteries)
• (12:45) NFC Instantly pairs Bluetooth - Fruit Ninja opens, app transfers to a second Nexus S.
• Ice Cream Sandwich (13:55) What we are showing you is just the tip of the iceberg
• (14:25) A new peer-to-peer interaction model (See NFC Peer-to-Peer Standards first specified in May 2009)
• 0-click contact sharing - Open a contact on a phone and bring near another phone and the contact is shared.
• 0-click web page sharing - Load a web page on one phone and bring another phone nearby and the web page is shared.
• 0-click YouTube video sharing - Start a video on a phone and touch a tablet and the video starts on the tablet where you left off.
• 0-click app sharing - Open an app on one phone, touch to a phone without that app. Android Market opens to download the app. Viral app sharing.
• Bluetooth + NFC == Wireless Nirvana (37:50) Initiate with NFC, switch to Bluetooth right away for the heavy lifting
• Privacy (39:25) Proximity - NFC is not RFID (a passive ID)
• On Android, NFC is off when the screen is off (no butt sniffing)
• 3rd party applications must be in the foreground to use NFC.
