With Android 2.3 Gingerbread, Google for the first time added Near Field Communication (NFC) support in their Operating System. NFC, as the name suggests, is a promixity-based connectivity option which can be used for transactions and transfers. 2.3 only let users read NFC data, but that has now been upgraded with the 2.3.3 update.
According to Android Developers Blog, the new update adds the following NFC features:
- 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.
Apart from the API level 10, the 2.3.3 update is nothing special. If you’re interested though, you can check out the release notes here.
