Everyone has been making a big deal about NFC lately - which phones have it, where it can be used, etc. Until last night's announcement, many (including myself) didn't see much on the horizon except a fun way to pay for things using your phone. That perception has changed, however, thanks to Android Beam.
Beam utilizes NFC technology to quickly, seamlessly transfer data from one device to another. As demonstrated last night, one has only to touch the two devices together to send just about anything from web pages, to photos, to apps.
Just touch the devices back-to-back, tap the confirmation, and that's it.
