One small tap for mankind: Exploring NFC

Submitted Oct 12, 2014

NFC on Android is not just about payments. There are a plethora of actions achieveable by that small tap of your phone, and surprisingly, NFC hasn’t been applied to as many fields as it should have been.


My idea is present my expriences while exploring the NFC platform. The applications of NFC reader capabilities present on a phone, as well as the beaming and auto-pairing functionalities.

NFC, being a low powered hardware, means speeds are in the range of 5kbps, but that is enough for small chunks of data. The best part is there is no need of pairing. Just the phones must be tapped onto each other, i.e. their backs touching each other as long as the communication takes place, and everything will be taken care automatically by the apps.


If you want to try it out in real time during the presentation, a phone/tablet with Android 4.4 or above with NFC and another phone/tablet with NFC and Android 4.2 or above will be needed.
And a laptop to develop the app on.
