Android 2.3 Gingerbread, released in December 2010, is an Android mobile OS version that followed Android 2.2 Froyo, with the addition and updation of numerous features. Currently, Gingerbread is the most widely deployed Android OS version on Android smartphone devices till date, since it can work on lower-end devices; and many such devices are still being released with it. The last stable version of Gingerbread, 2.3.7, was released in January 2011 and it already amounts to 54% of all Android deployed devices. Android OS Version 3.1 named Honeycomb followed the Gingerbread version.
Gingerbread 2.3 succeeded in providing an improved interface that's simpler, faster, refreshed and power-efficient. Along with supporting large screens, this version started accommodating features like intuitive text input with intelligent cut-and-paste system, internet calling, amended application and download manager, and NFC (Near-field communications) Reader application.
NFC is one of the key features of Android 2.3 uses a set of smartphone standards for radio communication between two devices. NFC devices pair with NFC tags or stickers which can be programmed by NFC apps in tasks automation. Possible types of tasks include a change of phone settings, a text to be created and sent, application launching, or any other commands to be executed.
For example, while checking out products in a supermarket, instead of scanning using a barcode reader, an NFC enabled cellphone will be able to automatically scan NFC tagged products and payment can be done directly through the cellphone through a saved credit card number for example.
