What is NFC (Near Field Communication)?
NFC is is a set of short-range wireless technologies, typically requiring a distance of 4 cm or less. NFC operates at 13.56 MHz and at rates ranging from 106 kbit/s to 848 kbit/s. NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target. This enables NFC targets to take very simple form factors such as tags, stickers, key fobs, or cards that do not require batteries. NFC peer-to-peer communication is also possible, where both devices are powered.
For end users of NFC-enabled Android devices, what this means is that applications now have more control about how they are launched when an NFC tag is read. For example, apps could listen for specific tag content or tag technologies, and only launch when a match was made. Plus, applications running in the foreground could stop another app from launching upon the tag reading event, if need be.

- A comprehensive NFC reader/writer API that lets apps read and write to almost any standard NFC tag in use today.
- Advanced Intent dispatching that gives apps more control over how/when they are launched when an NFC tag comes into range.
- Some limited support for peer-to-peer connection with other NFC devices.

Plus, applications running in the foreground could stop another app from launching upon the tag reading event, if need be.The updated platform also provides a limited peer-to-peer communication protocol and API for setting up things like Bluetooth or DLNA connections. That would mean that two NFC-enabled devices could share data when in close proximity. It's easy to imagine how developers could build apps for contact sharing or photo sharing using NFC.
Also new is the ability for developers to write tags, when before NFC allowed tag reading only. This two-way communication is an important aspect to any sort of NFC-backed mobile payment solution, such as the one Google is reportedly building now.
Google says it expects most devices shipping with an Android 2.3 platform will run 2.3.3 going forward.
NFC will let you make contact - free payment
Do not bother carrying your creditcard or cash money for any payment,you can just pay it all with your Android phone with NFC,just tag n tap and then gotcha!! Simple to making any payment. Thanks to the chips' short-range wireless capabilities, an NFC-enabled smartphone will allow you to simply wave your device in front of a retailer's sensor and have your purchase immediately placed onto your credit card or banking account.
Try it now and say thank you for Android 2.3.... :)
