Near field communication (NFC) makes it possible to exchange information between smartphones and other smart devices quickly. Uses for NFC on Android phones include file sharing, contactless payment systems, and programmable NFC tags.

Does NFC use power?

While newer Bluetooth Low Energy chips consume approximately 15 mA, energy consumption of a typical Bluetooth chip is twice as high. This means, NFC chips (5mA) consume three times less energy than Bluetooth Low Energy chips (15 mA) and even six times less than Bluetooth chips (30 mA).

Is NFC always on Android?
