NFC and Bluetooth are both short-range communication technologies that are integrated into mobile phones. As described in technical detail above, NFC operates at slower speeds than Bluetooth, but consumes far less power and doesn't require pairing. Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi. Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag"
